Common problems for air conditioners and dehumidifiers
- A very common problem resulting in poor air conditioner performance is a clogged air filter. Clogged filters can reduce your cool air output to zero and damage the compressor from undue stress.
- A broken thermostat can have a couple different effects on your air conditioner. It can cause it to not run at all or not stop running at the desired temperature.
- Dehumidifiers use an evaporator to cool incoming air so that moisture will condense and turn into liquid. The compressor or fan motor can burn out, requiring replacement.
- The fan in a dehumidifier blows air through the device. Broken blades, loose wires and other electrical problems can keep the fan from moving air through the dehumidifier.
- In order to cool the air coming into the evaporator, dehumidifiers require a refrigerant to run. Refrigerant can leak out of a damaged refrigerant line or a loose fitting.
Troubleshooting your faulty dehumidifier
If your dehumidifier won't turn on at all, the first thing to check is the power cord and outlet. Check the cord for damage and to see if it's loose. Next, check the outlet by plugging another electrical device into it. Reset the house circuit breaker for the outlet if it has no power. If the power cord and outlet check out fine, you'll need to open up the unit and make a visual inspection for loose wires or broken components. You can use a multimeter to check electronic components.
If the dehumidifier isn't reaching the desired humidity level, then it could have a problem with the compressor. Bad sensors or loose wires can also prevent the dehumidifier from removing moisture from the air.
