Your air conditioner has motors, electronic components, fuses, and wiring that all work together to keep the equipment working to cool your house. If your AC develops electrical problems, the air conditioner may not operate, or it may run erratically. It could even be dangerous to operate your AC when there are problems with the wiring. Here are some electrical issues that might come up and the repairs they could need.
1. Loose Or Damaged Wiring
Loose or damaged wiring can keep your AC from working properly. The way your air conditioner is affected depends on the location of the wiring problem. For instance, if the wiring is loose in the thermostat, the thermostat may not be able to trigger your AC to turn on or turn off. If wiring is loose, the air conditioning repair service can simply tighten the connections, but if the insulation is worn off or the wiring is corroded, then the wiring may need to be replaced.
2. Blown Fuse
Your air conditioner has its own power disconnect box with fuses. The fuses act as a safety measure and blow out if the air conditioner draws too much electricity because it is running continuously or struggling because of a clogged filter.
A repair technician can replace a blown fuse easily, but it's important to figure out why the fuse blew or it may just happen again. Changing the filter or cleaning the blower in the air handler might help, but your AC may need parts repaired or refrigerant filled so your air conditioner works normally and doesn't blow a fuse again.
3. Bad Electronic Parts
Your air conditioner has motors in the indoor air handler and also in the condenser outside. These motors need power to compress refrigerant, blow cool air through your house, or blow heat away from the condenser. In addition to wiring, the motor has electronic parts, such as a capacitor and contactor, that help the motor start up and run.
If a capacitor or contactor goes bad, your AC won't work properly and you'll need to have repairs done. For instance, if your blower won't start up, the capacitor on the blower motor may be bad. A service technician can replace the bad capacitor with a new one, and your AC will start up and run like it should.
Electrical problems with your air conditioner are an inconvenience, but you shouldn't operate your AC if it seems to be struggling to start or run. Instead, call an air conditioning repair service to inspect your AC, isolate the problem, and then make repairs.Share
