In the event that your heat pump stops working, the first thing you want to check is your thermostat. Is it set to “heat” or “cool” rather than “off”? If so, set it 5 degrees up if in heating mode or 5 degrees down if in cooling mode. Switch your fan to the “on” position.

At this point, your fan should be running. If it’s not, check your fuses and breakers. Has anything tripped? If so, turn it back to the on position or change the fuse if blown. Although your system may be functioning properly now, your problem is not over. There is a reason behind the blowing of the fuse or the tripping of the breaker. You may have faulty wiring, an issue with your blower motor, a problematic control board, a malfunctioning thermostat or even a bad heat pump. At this time, your best bet is to call a certified HVAC technician out to your home.

If your fan is indeed running, check to see if there is warm air coming from your vents. If there’s not, try switching to emergency heat. Still no warm air? You may have a bad thermostat or air handler. If there is warm air, it’s likely that your outdoor unit is to blame.

Return your thermostat to the normal settings. Make your way to the outdoor unit. Do you notice any ice or frost? If so, you may be low on refrigerant, have a bad control module or a bad defrost timer. No ice or frost? You may have debris such a grass, weeds, mulch etc blocking air flow. If none of those things seem to be the issue and the fan isn’t kicking on, you may need a new run capacitor, fan motor or simply new wiring as it can wear out over time.
