Problems with an HVAC Relay
A faulty relay or contactor can cause major problems for your heater or air conditioner. If you notice any of the following problems, then you can possibly blame a problematic relay. To confirm this diagnose and receive masterful repairs, contact ANC Mechanical, Inc.
Constant Operation: If your air conditioner or heater fails to shut-off unless you flip a breaker or pull the plug, then you likely have relay issues. This problem suggests a contactor that has become locked in place. When this happens, your heater or air conditioner receives a continuous signal for operation that overrides the thermostat.
Won’t Start: If your thermostat clicks on without a response from your heater or air conditioner unit, then you could have a relay problem. Even with orders from the thermostat, your system will not operate if it doesn’t have the high-voltage activation from the HVAC relay.
Overheating or Freezing Up: Your unit will only trip its emergency shut-off if it has run to the point of overheating or blowing out a motor. A faulty contactor often exists at the heart of this problem. At the same time, your air conditioner could freeze up from a bad relay. This happens when the unit has run for so long that its internal temperature falls enough to freeze condensation.
