A heat pump is a device that allows you to warm your home. However, it is possible for your heat pump to stop running without much warning. One of the main causes of your heat pump not running at all involves an issue with your thermostat obtaining power. If you notice that this is the issue you are dealing with, it is important for you to be aware of the steps that you need to take to correct the problem and allow for your heat pump to run normally.
It is important that you begin fixing the problem by checking to see that the thermostat is set properly. It might be possible that when you installed a new thermostat recently that you did not set it properly or that there is a wire that is malfunctioning. If you have installed a new thermostat recently, you need to be sure that you can rule out these two causes. These two issues can result in your heat pump not running.
You can next check to see if your heat pump is getting power. It might be possible that the circuits that are responsible for the heat pump power have tripped. You need to inspect the circuits to determine if they are working properly. Make sure that you not only check the main electrical panel, but also any sub panels that also supply power to the heat pump. If you notice that the circuit has tripped, you can correct the issue by just moving it from the off switch to on. Be sure that you keep an eye on the circuit to make sure that you do not have an issue with it tripping. If it trips often, you likely have a short.
If you have a heat pump that is connected to a power switch, you need to check to make sure that it is in the on position. It might be possible that this switch is within the air handler cabinet. If the switch is in the off position, this is typically the reason why your heat pump is not running. Just move it to the on position and give it a few minutes for the air handler to power on. This should not take any more than a few minutes to happen, so if you do not hear it engage within that period of time the issue was not corrected.
