AC Repair | Extraordinaire Case Files: AC that Won’t Turn Off


AC Repair | There are many reasons why AC owners need air conditioning service. One of them is because their AC doesn’t turn off put both the room and thermostat temperature the same level. There could be two reasons behind this. One of them is that the thermostat is at fault while the other reason being that the electrical system is present outside the condensing unit. Shutting off the unit by using the AC’s circuit breaker is one way of turning it off but it is not a permanent solution. You might require the help of an AC repair expert or you can check to see if the following solutions work for you:

AC installation

Check the thermostat. If it is blank, then it is the thermostat that needs to be replaced.

If switching the thermostat to HEAT shuts the AC off, then you will need to replace the thermostat.

If the thermostat is not the issue and works fine with the furnace, then the wires connected to it might be the problem. To check if that is the case, turn on your AC and remove the yellow low-voltage wire from the thermostat:

The thermostat will need to be wired correctly, if unit off. Check for cross-connected wires.

If that isn’t the issue, then replace the thermostat and see if that solves the problem.

If the AC doesn’t turn off, the contacts located on the outside might be welded together. In that case, turn the AC off and pry them apart.
