Air Conditioning Troubleshooting Guide Is your thermostat set in the "cool" position (or “warm” for winter heat pump operation)? If so, is  your outdoor air conditioning or heat pump unit running? Did the circuit breakers in the circuit breaker box (or electrical panel) trip to the “OFF”position? Is the outdoor "disconnect switch" on your outdoor unit in the "ON" position? (The disconnect switch is usually a small metal grey box mounted on a wall near the outdoor unit.) Is the blower motor in your furnace or air handler running when your thermostat is activated? (Make sure the furnace switch is in the "ON" position.) Have you changed your filter?

(A blocked filter can cause your unit to shut down due to lack of proper airflow.) Are the air registers (supply or return ducts) plugged? Gas Furnace Troubleshooting Guide Is your thermostat set in the "heat" position? Is the temperature setting on the thermostat set higher than the thermostat's indoor temperature? Is the power turned on for your furnace? (At the thermostat, turn the fan to "ON." The fan should run when  power is being supplied to the furnace.) Did the circuit breakers in the circuit breaker box (or electrical panel) trip to the “OFF”position? (Check the SSU light switch on the gray box located at the furnace to make sure it is in the "ON" position.)

Then return the switch to the normal setting. If the heat doesn’t come on even when the thermostat is set above room temperature, the problem is usually a lack of power caused by a tripped circuit breaker or blown fuse. In this article, we’ll show you how to deal with heat pump power problems; improper heating, cooling, and cycling; If these simple steps don’t work, have a heat pump repair technician check out your system. Note: If the weather is particularly cold and your heat pump doesn’t seem to be working right, please see Heat Pump Cold Weather Problems. If your heat pump doesn’t go on at all, there is a problem with the thermostat or the unit receiving power. 1Be sure the thermostat is set to the proper setting (Heat if you’re calling for heat and the temperature you want the room to be). If the thermostat was replaced recently, the new thermostat may either be the wrong type (it must be made for heat pumps) or it may have been wired improperly.

A mistakenly wired thermostat can fry electronic components, preventing the heat pump from working properly. 2Be sure the heat pump is receiving power. The two circuit breakers that protect the electrical circuits providing power to the air handler and heat pump condenser may have tripped. Check both the main electrical panel and any subpanels that supply power to the unit. If either circuit breaker has tripped, reset it by flipping it to OFF and then to ON. If the circuit breaker trips again, there is probably a short in the electrical system providing power to the furnace. Call an electrical contractor. 3If the heat pump is connected to a power switch, either on the wall near the unit or inside the air handler cabinet, be sure it is turned on (many don’t have switches). If it is turned off, turn it on and wait a few minutes for the air handler to engage. 4If your heat pump has electrical elements that provide supplemental heat (most do), the circuit breakers or fuses that protect the heating elements, which are usually located in the air handler cabinet, may have tripped or blown.

HomeTips Pro Tip: Opening up the cabinet of a heat pump and working with electrical parts can be dangerous for the inexperienced. If you don’t have the necessary knowledge and skills, call a heating repair technician. Heat pumps don’t discharge air that is as hot as the air discharged by oil or gas forced-air furnaces, so don’t expect their output to feel like that of a furnace. But if you’re used to a certain temperature of air and your heat pump is producing much cooler air, take the following steps. (Note that a heat pump may go into a defrost mode to prevent icing up. When this happens, it can temporarily output cold air. Also be aware that the heat pump will have to work harder to produce heat. 1Be sure the thermostat is set properly. Raise the set temperature 5 degrees F. and then wait a few minutes. 2Be sure the room-heating registers are open. 3Check the heat pump filter. If it is dirty, change it as described in the article How to Replace a Heat Pump Filter.

4Be sure the auxiliary heating elements are working (if your heat pump has these). 5Clean the coils of the outdoor condensing unit (see Central Air Conditioner Repairs). 6If these simple steps don’t work, have a heat pump repair technician check out your system—either the blower isn’t working properly or the system is out of balance in some other way. For example, the reversing valve may be stuck in the wrong position. It isn’t unusual for a heat pump to ice-up in really cold weather, but it’s defrost cycle should kick on periodically to melt the ice. If the condenser unit of the heat pump is frozen up and the defrost cycle doesn’t melt the ice, turn it off. Make sure none of the return-air registers are blocked, and check the filter to make sure it isn’t clogged. If there doesn’t seem to be a problem with air flow to the unit, see more information at Heat Pump Cold Weather Problems or call an HVAC service professional. If the power to the heat pump goes out, be aware that most heat pumps have auxiliary heating elements that provide heat when the weather gets really cold and the heat pump’s efficiency drops too low.

These elements automatically turn on at a fairly low temperature—around 20 degrees F. When they come on, they may be drawing too much power, which can trip the circuit breaker. Just locate the circuit breaker that serves the heat pump and reset it. This may be caused by one of two things: the thermostat mounted on the wall or the limit switch located on the heat pump just below the plenum (the box that distributes heated air to all of the ducts). The limit switch in a furnace or heat pump is designed to shut off the heat pump if the air in the plenum gets too hot. Check the thermostat to see if the Fan switch has been turned on. If it has, turn it to OFF or to Auto. If it is set to OFF or Auto already, the heat pump’s limit switch needs to be adjusted. Call a heat pump repair technician to make the adjustment or, if you are handy with this type of repair, follow the instructions in your owner’s manual to reset the pointers on the fan side of the limit control. The lower pointer should be set to about 90 degrees F. and the upper one should be at about 115 degrees F.

If the motor runs but the blower doesn’t move air, the belt that connects the two probably has broken. Replacing it is an easy fix: 1Turn off all power to the unit. Remove the door on the front of the air-handler cabinet to give you access to the blower (it may be on a slide-out drawer.) Check the number stamped on the belt and get an exact replacement from a home improvement center or heating supply outlet. 2Slip the belt on the motor’s (smaller) pulley first and then start it on the blower pulley, as shown at right. Rotate the blower pulley by hand, holding the belt in place but taking care to keep your fingers from getting caught between the belt and the pulley. The belt should slip right into place. 3If the belt seems too tight or difficult to put on using this method, it may be necessary to adjust the motor mount to provide more slack. Then just re-tighten the tension once the belt is in place. Check the manufacturer’s specifications for proper tension—in most cases, the belt should deflect about an inch when you press down on it.

When a heat pump turns off and on too frequently, the problem may be that the unit is overheating because of a clogged filter or blower that is malfunctioning. Try cleaning or replacing the filter. Then check the thermostat, which is more likely the cause. It usually means that the thermostat is improperly calibrated or that it is installed where it doesn’t sense a proper sampling of room air. If the thermostat has been located there for a long time and the heat pump has worked fine before, the latter case is not the issue. When room temperature rises higher or drops lower than the set temperature on the thermostat, the problem is usually the heat anticipator in the thermostat. If that doesn’t do the trick, call a heat pump repair technician. Squealing sounds and grinding noises are not good. Shut off the unit and call a heat pump repair technician—the motor’s bearings are probably shot. If the heat pump makes rattling noises when it runs, be sure the cover panels are screwed on tight.
