2. The AC short cycles often.
3. The thermostat display unit is blank.
4. Your AC is not working.
How To Fix It Yourself
Before calling the HVAC technician, here are a few things that you can do –
1. Check For Tripped Breaker Or Blown Fuse – The first thing to check is whether the thermostat is receiving power or not. For this, you will have to check in the fuse box or the main electrical panel. If the circuit breaker is tripped, push it back in the proper position. If the fuse is blown, you will have to replace the fuse wire or the entire fuse. Both these jobs can be performed by you.
2. Low Or Dead Batteries – Some thermostats use batteries as the power source. If your thermostat uses batteries, it may be time to change them. With constant use, the battery charge may have dropped drastically, or it could be completely dead. Replace the old batteries with new ones of the same power.
3. Check For Buildup And Debris In The Thermostat – Once you are sure that the thermostat is receiving power, its time to inspect the inner components. Shut down the thermostat breaker and unscrew or take off its front panel. Check for any sort of buildup on the electrical and mechanical components. It could include dust, grime, soot, or dirt. Use a soft brush or canned compressed air to get rid of these unwanted particles.
4. Check For Loose Wires And Corrosion – Now that the front panel is open, you might as well check for any loose connections or signs of corrosion on the terminals. If there are any loose wires, tighten them. If a wire is hanging free, you can use the wiring schematic in the owner’s manual to fix it to the correct location. In case there is corrosion on terminals, use a terminal cleaner to clean them.
