Lennox Heat Pump Not Defrosting? Here's What to Do
Heat pumps and air conditioners have been a trusted source of comfort in both homes and businesses for decades. With all the advancements made in technology, many of us have come to rely on them for reliable climate control. Unfortunately, sometimes issues can arise with these systems that require troubleshooting and repairs. If you’re dealing with a Lennox heat pump not defrosting, the following advice will help you diagnose and adjust the issue.
Understanding Heat Pumps and Defrost Cycles
A heat pump is a unique type of cooling system that uses refrigerant to move heat from one place to another. In the summer, it works as an air conditioner by taking the heat from your home and sending it outdoors. In the winter, the heat pump reverses its operation to bring heat into your home. A defrost cycle is one that helps keep the system running smoothly, by removing any built-up frost or ice on the outdoor unit.
What Causes Your Heat Pump Not to Defrost?
If your Lennox heat pump is not defrosting, the cause could be one of several culprits. The most common reasons for this type of issue include poor airflow over the outdoor unit, a malfunctioning thermostat, or an issue with the wiring or other components of your system. You may also have a problem with the fan or the compressor not running correctly.
Solutions for Lennox Heat Pump Not Defrosting
If your system is not defrosting, there are several steps you can take to troubleshoot the problem and get it running again. First, start with troubleshooting the thermostat. Make sure it’s connected to the correct type of power source and that it is calibrated to the correct temperature setting. If the thermostat is not the issue, check the fan, compressor and wiring to ensure they are running properly. Additionally, check around the outdoor unit to ensure that there are no obstructions, such as leaves or debris, blocking the intake or exhaust vents.
Finally, inspect the outdoor unit for excess frost or ice. If your system is still not defrosting and you’ve been unable to identify the source of the issue, it’s best to call a local reliable appliance repair service for assistance. They can provide expert diagnostics to identify the cause of the issue and offer the best solution for repair or replacement.
If you’re dealing with a Lennox heat pump not defrosting, the first step is to identify the cause. By troubleshooting the thermostat, fan and wiring, and making sure there are no obstructions around the outdoor unit, you may be able to identify and correct the issue yourself.

FAQ: Lennox Heat Pump Not Defrosting
What is the cause of Lennox heat pump not defrosting?
The cause of a Lennox heat pump not defrosting can vary. It can be due to a range of issues, such as a clogged condensate drain line, evaporator coils that are frozen, a defrost board that is faulty, or a compressor malfunctioning.
What should I do if my Lennox heat pump is not defrosting?
If your Lennox heat pump is not defrosting, there are a few steps you can take to troubleshoot the issue: check the fan blade, clean the condensate drain, check to make sure the coils are not frozen, replace any bad components, and make sure the compressor is running properly. If you continue to have issues, it is best to consult a professional.
What should I do if my evaporator coils are frozen?
If your evaporator coils are frozen, you should switch your heat pump to the “defrost” mode to allow it to defrost the coils.
