Julian Vivero Shares What Causes Smoke from a Heat Strip
HVAC Technical Academy
Sanford, Florida
May–June Session
Hello everyone. My name is Julian. We’re here at HVAC Technical Academy.
Today I’m going to be talking about a contactor.
A contactor is like a high-voltage switch.
When the thermostat calls for cooling or heating, it sends 24 volts to the contactor. The contactor pulls in, allowing high-voltage power to flow to the compressor and the condensing fan motor.
The contactor is located right over here in your condensing unit.
And if this fails, your system might not run properly or it might not run at all.
So, a contactor can go bad by electrical arcing, or debris can get in there between the contacts, and bugs can get in there as well, preventing the contactor from pulling in.
So, that’s all I got for you today.
Thank you very much for watching and I’ll see you on the next one.
