What happens when a contactor goes bad?
If the contactor is bad, the AC unit will lose its ability to adequately cool the home and may run continuously, even when the thermostat is turned off. Another visible sign is a burned contactor which is likely the result of wire insulation breaking down over time, which can eventually lead to electrical failure.
When should a contactor be replaced?
The coil can become shorted, grounded, or open. Your technician will use a meter to determine the resistance crossing your contactor. If the readings are outside of a very narrow range; your contactor should be replaced.
