You need to be familiar with your wirings when troubleshooting your heat pump. But what if you cannot find the fuse of your heat pump and you forgot where you put the machine's manual? No worries! You'll find out in this post where the fuse is in different brands of heat pumps. We've gathered information that will serve as your guide.
The heat pump fuse is usually within the electric board inside the machine. It is a colored metal-detachable clip. It has a plastic covering with two metal teeth attached to the electric board. It is easy to locate once you open your heat pump and look at the electric board.
Look at the fuse location of different heat pump brands:
- Payne: The fuse is on the lower part of the electric panel. Open the cover and find the panel inside the machine.
- Carrier: The fuse is close to the heat pump compressor.
- Bryant: The fuse is on the right side with a 5 amp tag.
Fuse is commonly found in electrical areas or panels. Stay on the page to find out the detailed location of more heat pump brands and how to manage some general troubles you may encounter with your heat pump.
Heat Pump Fuse Location [Inc. Payne, Carrier, Bryant & More]
Look at the machine's diagram to help you pinpoint the different parts of the heat pump, especially the small elements. Some brands have the parts and label posted on the cover panels.
Payne Heat Pump Fuse
Payne heat pump has its fuse on the electric panel. It is on the lower part. Below are the compressor and PCB assembly.

Reasons Heat Pump Fuse Keeps Blowing
The fuse is an integral system of your heat pump. It may have common mishaps, but overall it serves for safety and fire prevention. You use a fuse in compressors, motors, evaporating coils, and wiring configurations. It guards these elements in case of overheating. Also, it protects other heating and cooling pieces from overloading.
A heat pump fuse that keeps blowing may be caused by the following:
- Accumulated dirt and dust cause overheating and burnout.
- Loose wires create a short.
- Broken parts produce noises.
- Malfunctioning run capacitors show various electrical problems.
- A broken transformer causes trippings.
- The wrong fuse size cannot take the wattage needed.
- A faulty thermostat wire may rub the steel frame.
- Insufficient airflow can cause the blower not to function as it should.
- Water leaks further damage your machine.
- The extremely low temperature makes the system bolt enough power and can trip the circuit.
Heat Pump Common Issues
A heat pump trips or gets damaged like any other home machine or appliance. It is good to be aware of the usual mishaps you may encounter. It is also necessary to know some maintenance and fix guides regarding your heat pump. It can save you from service fees. Don't forget to handle your machine carefully and correctly.
Water Leak (Inside/Outside)
The water leaks inside of your machine because there is clogging of the condensate drain. Water leaks from your outside machine can be because of a damaged or faulty condensate pan or because the air filter is dirty.
Use a vacuum or a towel to clean the parts and filters of your heat pump. Thoroughly clean the unit and get rid of foul odor with a bit of distilled white vinegar. Call a technician for more serious fixes, especially for the outdoor unit.
Poor Heating Or Cooling
Your heat pump is not heating or cooling as it should because of different reasons. The thermostat does not set correspondingly, the system parts are dirty, and the outside of your heat pump is dirty or clogged. Another reason is the refrigerant charge is insufficient, the iced evaporator coil, or a faulty reversing valve.
Replace the air filter and schedule regular cleaning and maintenance of your heat pump filters and outdoor parts. Do not attempt to clean the intricate or electrical parts of the unit, though, for your safety. Call a service technician if it needs deep or overall cleaning.
It is a common condition with heat pumps and air conditioning units. It is because the condensate drain is clogging, moist filters, a buildup of fungi, leaks in refrigerant, and more.
The simple solution is replacing the filter and cleaning the clogged drain. You need to call a technician if the smell persists after.
There may be loose wires and connections inside your unit. A rattling noise indicates some loose pieces, while a clicking noise when turning on can mean a faulty starter capacitor. A squeaky noise may mean a more significant issue with your unit, so you need to call a service technician.
Resetting A Heat Pump
A heat pump running well is a must on cold days. A heat pump that is not turning on or responding needs resetting. There are reset buttons for most HVAC systems. Check your manual's instructions for your heat pump's reset button. Some units have two reset buttons, one on the outside and one on the inside.
Follow this easy guide to resetting your heat pump:
- Shut down the main power to the heat pump.
- Locate the reset buttons for the inside and outside units.
- Press the reset buttons. Switch off the power if there are no reset buttons.
- Let it cool or stay for 2 to 3 minutes.
- Switch on the unit. It will be working fine by then.
- Call for further help if you turn on your heating unit, but it automatically shuts down on its own. There may be extensive issues with your heat pump.
How Do You Tell If Your Heat Pump Is Not Working?
There is a lot of usage of heat pumps in places where winter takes longer. Maintain and regularly check your heat pump for the freezing season throughout the year to avoid accidents and dangerous fixes in the middle of winter.
Here are some situations that should serve to warn you that your heat pump is not functioning as it should. Call a technician when it happens.
- Your heat pump is icing up during winter.
- Your heat pump is icing up during summer.
- Your heat pump keeps cycling on and off.
- Your heat pump blower ceased working.
- Your heat pump creates unusual noises.
- Your heat pump is poorly functioning while bills go up.
- Your heat pump produces poor indoor air quality.
How Do I Check A Heat Pump?
You can check it through your thermostat. Set it to heat and let the warm air travel throughout the room. See if the vents are releasing some warm air. Afterward, see the outdoor system and observe if it's active and going. If it does, you have a healthy heat pump.
Also, you can determine if you have a heat pump rather than a standard AC if your thermostat has an emergency heat setting. It has the label EM, EMER, or EMERGENCY on your thermostat.
The heat pump fuse of different brands may have the same location inside the unit. Carefully take off the unit cover and slowly scan or browse a card blade-type fuse. It is similar to an automotive fuse, a thin and tiny piece detachable clip. One way to be sure is to read through the unit's manual or diagram.
