my heat and ir will come on then stops comes back on a second and repeats shuts off then comes back on
As in the fan blowing the heat cycles on and off or the heat itself cycles on and off…I’m a little bit confused as your post isn’t clear…
the air and heat do work, just when i turn either on, it will work for 20 seconds then shut down 10 seconds and come back on and repeat
so the fans are cutting in and out? I would check the fuse for the blower, also check the resistor if you have a multimeter.
Thank you, mark
