If the fan is not turning, but you hear the compressor running, then something is wrong (unless as noted above with defrost mode), and you need to call a professional. The condenser fan motor is located in the outdoor unit. That is normal, and a part of the automatic defrost mode for the heat pump. Is the condenser fan motor turning at the heat pump condenser? Word of note - sometimes in the winter or when you have the heat pump in heating mode, the fan will not turn while the compressor is running. If the heat pump blower runs all the time check here. The step for heat pump troubleshooting is to check the airflow. In any of these cases, it is time to call an HVAC repair service. Maybe a bad heat pump blower motor, the unit is freezing up inside the evaporator coil, or collapsed ductwork. If this is all good, then you have another problem with the airflow. Always make sure you have a clean air filter and that all of your supply vents are open and unobstructed. Is the air handler blower working well and blowing air out of all of the supply vents? If not or it is weak, then you likely have an airflow issue. Clean filters are essential to good indoor airflow. Sometimes the air filter is located in a filter rack and other times the air filter is located in the air handler. You should know where the air filter is located. The air handler is typically located inside. Step 3 for heat pump troubleshooting is to check for ice or freezing. It is best to call a pro to fix that issue. That could mean the defrost mode isn’t working properly and may need a minor adjustment or a repair altogether. In the winter, check the condenser (outdoor unit) does not have excessive ice on the coils. If you find no problems leave the unit turned off, and call a service company. In the summer, if the evaporator coil has ice on it or any of the copper pipes have ice on them, then you have a problem that needs the attention of a professional. Air filters are essential to the operation and need to be clean. Check the air filter(s) to make sure they are not clogged or obstructed in any way. If the air heat pump unit is frozen, turn it off. In the summer check for freezing up of the heat pump. Ice or Freezing | Hate Pump Troubleshooting No Heat Step 2 in heat pump troubleshooting is to check the power supply. One for the condenser and one for the air handler. A typical split system will have separate breakers. Make sure you check the breaker at the air handler and the breaker in the main panel. These switches are typically not on heat pumps as a heat pump liking has a breaker next to the heat pump. Perhaps relatives were visiting, and someone mistook the wall switch for a light switch. I have responded to heat pump no heat or heat pump, not cooling calls, only to find the power was off inadvertently. That can include a heat pump circuit breaker and or/a regular-looking wall switch close to the unit. Finally, for heat pump troubleshooting, this is always the first place to start. For example, if you want the heat pump to heat, make sure the thermostat is set to heat.įurthermore, if the temperature in the house is 65° F, make sure you turn the thermostat setting up above 65° F. Additionally, make sure the set point is correct. I found they had the thermostat set to heat when they wanted to cool. I’ve responded to service calls where the homeowner made a no heat or no cool call. Ensure that the setpoint setting is at the desired settings.
