Troubleshooting the Dreaded ERL Error on Your Pit Boss Pellet Grill

The dreaded “ERL” error. These three letters can strike fear into the heart of any Pit Boss pellet grill owner. It appears on the digital control panel, often during a crucial smoking or grilling session, and signals a problem with the temperature reading. But don’t despair! This comprehensive guide will walk you through the steps to diagnose and fix the ERL error, getting you back to grilling those delicious meals in no time.

Understanding the ERL Error Code

The ERL error on a Pit Boss grill essentially means the control board is detecting a temperature reading that is outside of the acceptable range. This could be due to a faulty temperature probe, a problem with the wiring, or even a malfunction in the control board itself. Understanding the possible causes is the first step toward resolving the issue. It’s crucial to rule out simple fixes before jumping to more complex solutions. Often, the issue is simpler than you might initially expect.

What Does ERL Really Mean?

ERL isn’t an acronym for anything specific in the Pit Boss world. It simply denotes an “Error Low Reading.” The control board expects a temperature reading within a certain range. When the temperature probe sends back a value that is too low, or doesn’t send back any value at all, the ERL error is triggered.

When Does the ERL Error Typically Appear?

The ERL error can pop up at various times during the grilling process. You might see it when you first turn on the grill, during the initial startup phase, or even after the grill has been running for a while. Sometimes, it appears intermittently, making diagnosis more challenging. The timing of the error can sometimes provide clues as to the underlying cause.

Diagnosing the Cause of the ERL Error

Finding the root cause of the ERL error requires a methodical approach. Start with the simplest and most common issues and then move on to more complex possibilities. Always ensure the grill is unplugged and completely cool before attempting any repairs or inspections.

Checking the Temperature Probe (RTD Probe)

The temperature probe, also known as the RTD (Resistance Temperature Detector) probe, is the most likely culprit. This probe is responsible for sensing the temperature inside the grill and relaying that information to the control board.

Visual Inspection: Begin by visually inspecting the probe. Look for any signs of damage, such as cracks, breaks, or corrosion. Pay close attention to the wiring connected to the probe. Make sure the wires are securely connected and not frayed or broken.

Cleaning the Probe: A dirty probe can sometimes cause inaccurate readings. Use a clean, dry cloth to wipe down the probe and remove any accumulated grease, soot, or debris. Avoid using harsh chemicals or abrasive cleaners, as these could damage the probe.

Testing the Probe with a Multimeter: If a visual inspection doesn’t reveal any obvious problems, you can test the probe’s resistance using a multimeter.

  • Unplug the grill from the power outlet.
  • Locate the temperature probe wires connected to the control board.
  • Disconnect the probe wires from the control board.
  • Set your multimeter to the resistance setting (Ohms – Ω).
  • Place the multimeter probes on the two terminals of the temperature probe.
  • Compare the resistance reading with the expected value. This value varies depending on the probe and the ambient temperature. Generally, a healthy probe will show a resistance that increases as the temperature rises. Contact Pit Boss customer service or refer to the probe’s documentation for the specific resistance value at a given temperature. If the reading is significantly off or shows an open circuit (infinite resistance), the probe is likely faulty and needs to be replaced.

Inspecting the Wiring and Connections

The wiring connecting the temperature probe to the control board can also be a source of the ERL error. Damage to the wires or loose connections can disrupt the signal and cause the control board to misinterpret the temperature.

Following the Wires: Carefully trace the wires from the temperature probe to the control board. Look for any signs of damage, such as cuts, crimps, or abrasions. Pay close attention to areas where the wires might be exposed to heat or friction.

Checking the Connectors: Inspect the connectors where the wires attach to the temperature probe and the control board. Make sure the connectors are clean, secure, and free of corrosion. If you find any corrosion, clean the connectors with a wire brush or electrical contact cleaner. Ensure the connectors are fully seated and locked in place.

Testing Wire Continuity: Use a multimeter to test the continuity of the wires. This will verify that the wires are not broken or damaged internally.

  • Unplug the grill from the power outlet.
  • Disconnect the wires from both the temperature probe and the control board.
  • Set your multimeter to the continuity setting (usually indicated by a beep symbol).
  • Place the multimeter probes on each end of the wire.
  • If the multimeter beeps or shows a low resistance reading, the wire has continuity and is good. If the multimeter does not beep or shows a high resistance reading, the wire is broken and needs to be replaced.

Examining the Control Board

The control board is the brain of the Pit Boss grill. It receives the temperature reading from the probe, controls the auger and fan, and displays information on the digital panel. Although less common than probe or wiring issues, a faulty control board can sometimes be the cause of the ERL error.

Visual Inspection: Carefully inspect the control board for any signs of damage, such as burnt components, swollen capacitors, or cracked traces. These are signs that the control board may be malfunctioning.

Checking the Connections: Make sure all the connectors on the control board are securely seated. Reseat all connections to ensure good contact.

Considering Replacement: If you suspect a faulty control board, the best course of action is to replace it. Control boards can be sensitive electronic components, and troubleshooting them requires specialized knowledge and equipment.

What does the ERL error code on my Pit Boss grill actually mean?

The ERL error code on a Pit Boss pellet grill generally indicates a problem with the temperature sensor, often referred to as the RTD (Resistance Temperature Detector) probe. This probe is responsible for measuring the internal temperature of the grill and relaying that information to the control board. When the control board detects an issue with the signal coming from the RTD probe, such as a short circuit, open circuit, or implausible temperature reading, it triggers the ERL error as a safety measure to prevent the grill from malfunctioning or overheating.

Essentially, the grill’s computer is saying it can’t reliably “see” the temperature inside the cooking chamber. This lack of reliable temperature information can lead to uncontrolled heating or failure to maintain the set temperature. Consequently, the grill will likely shut down to prevent potential damage to the grill or your food. Before assuming a faulty probe, consider other potential causes like wiring issues or a damaged control board.

How do I check if the RTD probe is the cause of the ERL error?

The first step in diagnosing a potentially faulty RTD probe is a visual inspection. Carefully examine the probe itself for any signs of physical damage, such as cracks, breaks, or melted areas. Also, check the wiring connecting the probe to the control board. Look for frayed wires, loose connections, or any signs of rodent damage. Disconnect and reconnect the wires to ensure a secure connection.

Beyond the visual inspection, a multimeter can be used to test the probe’s resistance. Consult your Pit Boss grill’s manual or online resources to find the expected resistance range for the RTD probe at room temperature. If the multimeter reading falls significantly outside this range, it suggests the probe is defective and needs replacement. Remember to disconnect the grill from power before performing any electrical testing.

What if the RTD probe seems fine, but I’m still getting the ERL error?

If a multimeter reading suggests the RTD probe is functioning within its expected parameters, the issue might lie in the wiring connecting the probe to the control board. Carefully trace the wires from the probe, ensuring they are not pinched, cut, or exposed to excessive heat. Pay close attention to any connectors or junctions in the wiring, as these are potential points of failure. Use a multimeter to check for continuity along the entire length of the wiring, looking for any breaks or shorts.

Alternatively, the problem could reside within the control board itself. The control board is the brains of the operation, processing information from the RTD probe and controlling the auger and fan. A faulty control board might misinterpret the signal from a perfectly good RTD probe, leading to the ERL error. Before concluding a control board issue, confirm the wiring is good and consider the possibility of a loose connection on the board itself. Replacement of the control board is generally required in this scenario.

Can weather conditions affect the ERL error on my Pit Boss grill?

Extreme weather conditions, particularly high humidity or moisture, can indeed influence the occurrence of the ERL error. Moisture can seep into connections, corrode wiring, or even penetrate the RTD probe itself, leading to inaccurate temperature readings or short circuits. This is more prevalent if the grill is stored outdoors or exposed to rain or snow.

During periods of high humidity, it’s advisable to thoroughly dry all connections and the RTD probe before starting the grill. Consider using a moisture displacement spray on electrical connections. Additionally, ensure proper ventilation around the grill to prevent moisture buildup. Storing the grill under a cover or in a garage during inclement weather can significantly reduce the risk of moisture-related issues.

Is there a way to reset the ERL error code on my Pit Boss grill?

In some cases, a simple reset can clear the ERL error code, especially if the error was triggered by a temporary glitch or a brief interruption in the temperature sensor’s signal. To attempt a reset, first, turn off the grill and unplug it from the power source. Allow it to remain unplugged for at least five to ten minutes. This allows the control board to completely discharge and reset its internal memory.

After the waiting period, plug the grill back in and turn it on. Monitor the display to see if the ERL error reappears. If the error is gone, allow the grill to run through its startup sequence and monitor the temperature readings to ensure they are accurate. Note, however, that a reset will only temporarily clear the error if the underlying problem persists.

What tools do I need to troubleshoot the ERL error?

A basic toolkit for troubleshooting the ERL error on your Pit Boss pellet grill should include a few essential items. First and foremost, a multimeter is crucial for testing the resistance of the RTD probe and checking for continuity in the wiring. A screwdriver set, including both Phillips head and flathead screwdrivers, will be necessary for accessing the control board and other components.

Additionally, wire strippers and crimpers can be helpful for repairing or replacing damaged wiring. A flashlight or headlamp is essential for illuminating hard-to-reach areas inside the grill. Finally, a can of electrical contact cleaner can be useful for cleaning corroded connections and improving signal transmission. Remember to always disconnect the grill from power before working on any electrical components.
