Ac Relay Getting Hot at Marcia Reames blog

Ac Relay Getting Hot. two things can make an electromechanical relay hot. Sometimes you can do whats called a 'hit and hold', the drawback is you need two switching. the fan relay controls the blower fan inside your indoor unit or air handler. if a relay operates too frequently it can generate higher levels of heat over time. High levels of heat in a relay can cause the failure of the coil, the fusing of the contacts, or ultimately the contacts welding together. If it fails to engage, your ac system will not start, leaving you without cool air. while 1 watt of heating power may seem little, it is enough to noticeably increase the relays temperature. The relay acts as the switch that allows power to flow to the compressor. This fan circulates conditioned air throughout your home and draws warm indoor air over the evaporator coil for cooling. The traces act like a heat sink, carrying the heat. If a relay is not installed correctly or subject to higher levels of voltage or current it can produce high levels of heat. When your thermostat calls for cooling, it sends a signal to the fan relay to turn on the blower fan. if you notice that your ac system fails to turn on when you activate the controls, it could be due to a bad ac relay. the relay will get very hot if you drive the diode.
