Lennox SL22KLV Heat Pump Error Code 107: Compressor Protection Mode Activated

When your Lennox heat pump model SL22KLV displays Error Code 107, you’re looking at a compressor protection issue that demands prompt attention to prevent further damage. The outdoor unit’s compressor switch is open, and the system is protecting itself from potential damage due to voltage protection or communication problems.

You’re likely wondering what’s causing this issue and how to fix it – look further to understand the causes of compressor protection, troubleshooting steps, and the importance of professional assistance to get your heat pump up and running again.

Understanding Error Code 107

Several Lennox heat pump models are prone to displaying Error Code 107, which indicates a specific issue that requires prompt attention.

When you see this error code, your Lennox heat pump’s outdoor unit is experiencing a compressor protection issue. This means the compressor switch is open, and the system is protecting itself from potential damage.

The issue could be related to voltage protection or a communication problem between the outdoor unit and the indoor mini-split. As an HVAC system owner, it’s vital to address this issue promptly to prevent further damage.

You’ll need to troubleshoot the problem to get your heat pump running efficiently again.

Causes of Compressor Protection

What’s causing your Lennox heat pump to trip into compressor protection mode?

Crucially, identify the root cause of code 107 to prevent further damage to your heat pump models:

• Compressor drive error: The compressor may be malfunctioning, triggering the compressor protection feature to prevent overheating or electrical damage.
• Voltage protection: The outdoor unit’s voltage sensor may detect an abnormal voltage supply, leading to compressor protection mode.
• Temperature sensor issue: A malfunctioning temperature sensor can cause the heat pump to misread operating conditions, resulting in compressor protection mode.
• Mini-split heat pump system faults: Issues with the refrigerant flow, valve operation, or other system components can trigger compressor protection mode in your Lennox heat pump.

Troubleshooting Steps for Error Code 107

Now that you’ve identified the possible causes of error code 107, it’s time to take corrective action.

For your Lennox heat pump model SL22KLV, follow these troubleshooting steps.

First, check the compressor protection feature, guaranteeing it’s not triggered by a faulty temperature sensor.

Next, verify that the mini-split system’s refrigerant levels are within the recommended range.

If you’ve recently installed the system, confirm that it’s been done, as improper installation can trigger error codes.

Finally, review the heat pump’s error codes to confirm you’re addressing the root cause of the issue, rather than just its symptoms.

Frequently Asked Questions

How Do You Reset a Heat Pump Compressor?

You’re stuck in a rut, like a car on a cold winter morning. To reset a heat pump compressor, check for compressor tripping, pump failure mode, or heat overload, then verify no electrical surge, cooling issues, or defrost mode issues exist.

How to Clear Lennox Error Code?

You’ll need to perform error code troubleshooting by interpreting the error message, identifying system shutdown reasons, and following diagnostic procedure steps to classify the error code, ultimately detecting faulty components and facilitating heat pump fault diagnosis for effective maintenance.

What Does CL Mean on Lennox Mini Split?

As you navigate the climate levels of your mini-split system, you stumble upon the mysterious “CL” code. It’s not about operating modes or system checks. CL actually stands for Compressor Lockout, a critical warning that demands attention to prevent filter warnings, temperature range issues, and pressure readings gone awry.

How Do You Reset a Lennox Heat Pump?

You reset your Lennox heat pump by pressing the reset button on the thermostat, switching to heat mode, and adjusting the fan setting, ensuring the error display clears, and then performing a system check for any fault indicators or temperature sensor issues on the control panel.

Conclusion

As you wrap up troubleshooting, remember that error code 107 is like a fire alarm: it’s not the problem, but a warning that something’s amiss. Don’t ignore it, or you might end up with a fried compressor. Take heed, and you’ll be back to cozy temperatures in no time.
