Find a Oestrus Pump Repair Pro Virtually You
If the heat doesn't come on even when the thermostat is set to a higher place room temperature , the problem is usually that information technology isn't receiving power because of a tripped circuit billow or diddled fuse.
Note: If the weather is particularly cold and your oestrus pump doesn't seem to be working right, please see Oestrus Pump Cold Weather Problems.
Heat Pump Does Non Run
If your heat pump doesn't get on at all, there is a trouble with the thermostat or the unit isn't receiving power. Exercise the following:
1 Exist sure the thermostat is set to the proper setting ("Oestrus" if you're calling for heat) and the temperature you desire the room to be. If the thermostat was replaced recently, the new thermostat may exist the wrong type—it must be specifically a heat pump thermostat. Or, it may have been wired improperly. An improperly wired thermostat can fry electronic components, preventing the heat pump from working properly.
2 Be sure the heat pump is receiving ability. The ii circuit breakers that protect the electrical circuits providing power to the air handler and heat pump condenser may take tripped.

Bank check both the main electrical panel and any electric subpanels that supply power to the unit. If a circuit breaker has tripped, reset it by flipping information technology to OFF and and then to ON.
If the circuit breaker trips again, there is probably a short in the electrical system that normally provides power to the furnace. Phone call an electrical contractor (go to HomeAdvisor).
3 If the oestrus pump is connected to a power switch, either on the wall nearly the unit or within the air handler cabinet (many don't have switches), exist sure the switch is turned on. If it is turned off, plough it on and wait a few minutes for the air handler to engage.
four If your heat pump has electrical elements that provide supplemental estrus as most do, the circuit breakers or fuses that protect the heating elements may have tripped or blown. They are ordinarily located inside the air handler cabinet. Reset them.
HomeTips Pro Tip: Opening upwardly the cabinet of a estrus pump and working with electrical parts tin can be dangerous for the inexperienced. If you don't have the necessary knowledge and skills, phone call a heating repair technician (HomeAdvisor).
Heat Pump Doesn't Heat or Absurd Correct
Heat pumps don't discharge air that is as hot every bit the air discharged by oil or gas forced-air furnaces, and then don't wait their output to feel like that of a furnace when they're on.
Just if you're used to a sure temperature of air and your oestrus pump is producing much cooler air, take the following steps.
Please notation: A heat pump may go into a defrost style to prevent icing upwards. When this happens, it can temporarily output common cold air. As well be aware that the estrus pump volition take to work harder to produce oestrus when in defrost manner and/or when information technology'due south particularly common cold exterior.
1 Be sure the thermostat is set properly. Heighten the prepare temperature 5 degrees F. then await a few minutes for the heat to come on.
2 Be certain the room-heating registers are open.
3 Check the heat pump filter. If it is dirty, change it as described in the article How to Supercede a Estrus Pump Filter.

4 Be sure the auxiliary heating elements are working (if your heat pump has these).
5 Clean the coils of the outdoor condensing unit (see Central Air Conditioner Repairs).
six If these simple steps don't work, take a oestrus pump repair technician check out your organization. Either the blower isn't working properly or the arrangement is out of balance in some other way. For case, the reversing valve may exist stuck in the wrong position.
Rut Pump Freezes Upward or Trips Billow
It isn't unusual for a heat pump to ice-up in really cold weather, but it'south defrost bicycle should kick on periodically to melt the ice. If the condenser unit of the rut pump is frozen up and the defrost cycle doesn't melt the water ice, plough it off.
Make sure none of the return-air registers are blocked, and then check the filter to make sure information technology isn't chock-full.
If at that place doesn't seem to be a problem with air menstruum 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 enlightened that most heat pumps have auxiliary heating elements that provide estrus when the weather gets actually cold and the heat pump's efficiency drops too low. These elements automatically plow on at a adequately low temperature—around 20 degrees F. When they come on, they may be drawing too much power, which can trip the circuit breaker. But locate the circuit breaker that serves the heat pump and reset information technology.

Estrus Pump Blower Doesn't Work
This may be caused past one of two things: the thermostat mounted on the wall or the limit switch located on the heat pump simply beneath 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 close off the heat pump if the air in the plenum gets too hot.
Check the thermostat to run into if the Fan switch has been turned on. If it has, turn it to OFF or to Motorcar.
If information technology is prepare to OFF or Auto already, the heat pump'due south limit switch needs to be adjusted.
Call a heat pump repair technician to make the aligning or, if y'all are handy with this type of repair, follow the instructions in your possessor's manual to reset the pointers on the fan side of the limit command. The lower pointer should be prepare to about xc degrees F. and the upper one should exist at about 115 degrees F.
If the motor runs just the blower doesn't move air, the belt that connects the two probably has cleaved. Replacing it is an like shooting fish in a barrel prepare, as discussed below:
HomeTips Pro Tip: Opening upward the cabinet of a heat pump and working with electric parts can be unsafe for the inexperienced. If you don't take the necessary knowledge and skills, call a heating repair technician (HomeAdvisor).
ane Plough off all power to the unit. Remove the door on the front end of the air-handler cabinet to give you admission to the blower (information technology may be on a slide-out drawer.) Find the cleaved chugalug. So check the number stamped on the belt and get an exact replacement from a home comeback middle or heating supply outlet.
ii Sideslip the belt on the motor's (smaller) pulley first and and so starting time it on the blower caster, as shown below. Rotate the blower pulley by hand, holding the chugalug in place but taking care to proceed your fingers from getting defenseless betwixt the chugalug and the pulley. The belt should whorl right into identify.

3 If the belt seems as well tight or difficult to put on using this method, it may be necessary to adapt the motor mount to provide more slack. Loosen the mount as shown below Then just re-tighten the tension once the belt is in place. Check the manufacturer'south specifications for proper tension—in almost cases, the chugalug should deflect about an inch when yous press down on it.

Heat Pump Cycles Incorrectly
When a rut pump turns off and on too frequently, the problem may exist that the unit is overheating because of a clogged filter or blower that is malfunctioning. Endeavor cleaning or replacing the filter.
Check the thermostat settings if your heat pump is cycling poorly.
Then bank check the thermostat, which is more probable the crusade. It usually means that the thermostat is improperly calibrated or that information technology 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 estrus 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 rut anticipator in the thermostat. See Thermostat Repairs.
If that doesn't exercise the trick, call a estrus pump repair technician.
Heat Pump Makes Noises
Squealing sounds and grinding noises are not good. Shut off the unit and phone call a heat pump repair technician—the motor'southward bearings are probably shot.
If the heat pump makes rattling noises when information technology runs, be sure the cover panels are screwed on tight. If they aren't, tighten them. Other noises may be coming from rattling ductwork or loose parts in the air handler.
Many heating ducts are metal, so they behave noise quite readily from the air-handling unit to your rooms. To interruption the conduction of audio, you can accept a heating contractor insert flexible insulation ductwork between the heat pump and the ductwork runs.
If you hear a pinging or popping audio coming from the ductwork, this may be caused by thermal expansion or by air bravado past a loose flap of metal. Rails along the duct runs, listening for the audio. If you find information technology, make a small dent in the sheet metallic to provide a more rigid surface that's less likely to move as it heats and cools.
