Lennox Heat Pump Not Defrosting? Here's What to Do
If your Lennox heat pump is not defrosting, you are likely frustrated and ready to call a repair service before the temperature outside gets any lower. Before you do, you should take a few steps to figure out the cause and see if there are alternative solutions to fixing the problem. With some simple troubleshooting, many times the issue can be easily resolved, saving you time and money.
Troubleshooting – Step 1
The first step in troubleshooting a non-defrosting heat pump is to locate the thermostat and check if it's set for the heating mode. If the thermostat settings are misunderstood and the thermostat is set to cooling, the defrost cycle won't be activated. To activate the defrost cycle, the thermostat needs to be set to the 'heat' mode.
If your thermostat is indeed on 'heat', you can check the outside air temperature next. If it's below fifty degrees Fahrenheit, the system won't enter the defrost cycle either. Adding insulation or a temperature blanket to the outside unit can help keep the ambient temperature above the minimum threshold.
Troubleshooting – Step 2
The second step of troubleshooting a non-defrosting heat pump is to inspect the outdoor fan coil unit. This is the part that houses the compressor, fan, and coils. If the fan fails to start, the unit won't defrost. Make sure there is power to the fan and the fan is spinning normally. If it's not, inspect to make sure nothing is blocking the fan and that it's turning freely. In some cases, the fan motor may need to be repaired or replaced.
The coil itself may be coated in ice or frost. This can prevent it from transferring the heat between the indoor and outdoor unit. If the coil is heavily frosted, you may need to turn the unit off and wait for the ice to melt. As the ice melts, turn the heat pump back on and observe if the fan turns on.
Troubleshooting – Step 3
The third step of troubleshooting your Lennox heat pump is to inspect the reversing valve, also called the four-way valve. This valve switches the flow of refrigerant between the heating and cooling cycles. If it gets stuck in the wrong position, the heat pump won't enter the defrost mode. The reversing valve is a delicate part and should only be checked by an HVAC technician who is trained and experienced in dealing with these types of valves.
Conclusion
A heat pump that won't enter the defrost cycle can be stressful and confusing. If your Lennox heat pump is not defrosting, you can try a few troubleshooting steps to find the problem and address it quickly.

Lennox Heat Pump Not Defrosting
The Lennox heat pump is a reliable and efficient HVAC system, however, it can experience issues with not defrosting. In order to prevent such an issue from occurring in San Diego, here are some manufacturer recommendations and/or local appliance and HVAC technician's recommendations:
-
Regularly Clean the Heat Pump – It is important to regularly clean and perform maintenance on the Lennox heat pump to prevent build up of dust or debris on the coil or within the cabinet. This ensures the heat pump is running efficiently.
-
Monitor the Ambient Temperature – The ambient temperature must be monitored in order to ensure the heat pump is operating in the temperature range it is designed to work in. When the ambient temperature is outside of this range, it is likely that the heat pump will not be able to defrost properly.
-
Check Ventilation and Air Filters – Ensure that the heat pump’s ventilation system and air filters are in good condition to give the heat pump enough air circulation. Also check the rear of the cabinet to make sure the rear diverter switch is in the correct position, and free of debris or clogs.
-
Inspect the Outdoor Coil – Make sure the outdoor coil is free of ice, dirt, or debris. If the heat pump does not have enough airflow, it will not be able to defrost.
-
Check the Thermostat Sensors – Make sure all the thermostat sensors are working properly and make sure the thermostat is calibrated to the correct temperature for the heat pump to properly defrost.
-
Monitor the Refrigerant Levels – Refrigerant levels must be maintained in order for the heat pump to properly defrost. Low refrigerant levels will cause the heat pump to not defrost.
In conclusion, there are several manufacturer recommendations and local appliance/ HVAC technician’s recommendations that can help prevent an issue with the Lennox heat pump not defrosting in San Diego. By regularly cleaning, monitoring the temperature, checking ventilation and air filters, inspecting the outdoor coil, checking the thermostat sensors, and monitoring the refrigerant levels, the heat pump will be able to work effectively and efficiently.

FAQ: Lennox Heat Pump Not Defrosting
Q: What should I do if my Lennox heat pump is not defrosting?
A: If your Lennox heat pump is not defrosting, the main culprit could be a faulty compressor, faulty reversing valve, or frozen outdoor coils. It's best to first check to see if the outdoor unit is completely free of ice and snow. If it is free of build-up, turn off the unit and look for loose or frayed wiring, corroded contacts, and debris buildup at the reversing valve. Additionally, check for any obstructions near the outside unit which could impede airflow. If all of these are in good condition, it is recommended to call a local, reliable appliance repair service for further evaluation and repair.
Q: Why is my Lennox heat pump not defrosting?
A: Many factors can cause a Lennox heat pump to not defrost. The most likely culprit is a faulty compressor, frozen outdoor coils, or a faulty reversing valve. Additionally, obstructions near the outside unit which could impede airflow, loose or frayed wiring, and corroded contacts should also be checked.
Q: What happens when my heat pump cannot defrost?
A: When your heat pump is unable to defrost, it may cause the unit to operate inefficiently due to the buildup of frost and ice on the outdoor coil. This results in the heat pump drawing more energy than usual to regulate the temperature, resulting in an increase in your energy bills. Additionally, it can also cause the unit to wear out more quickly as parts will be excessively overworked to compensate for the lack of defrosting.
To ensure your heat pump is running efficiently, it is important to arrange for repairs as soon as you notice a problem. If your heat pump is not defrosting, we recommend calling a local, reliable appliance repair service for more assistance.
