Myblower motor in the house the one that blows air thruthe vents shuts off when I turn the thermostat to ac but as soon as I change the thermostate to heat the blower turns on like nothing is wrong

Cooling relay is probably bad, what brand unit?

Coleman

The coils and the lines continue to cool and eventually freezes but no blower but as soon as I turn the heat on the blower works fine

Does your unit have a control board, or a relay box?

You mean outside by the main unit with 2 big looking fuse things

Josh wants to know whether the furnace has a large PC board in it or something like a Fan center.

The fan can be controlled very differently in the AC mode.

I'd like to know if the FAN comes on when you just move the FAN Switch to the ON position with the HEAT/OFF/COOL switch in the OFF position. I suspect not.

Outside there is a box and there are 2 breakersonthe blower ichecked the breakers on the blower its not or theyare not switched

The blower motor has like a almost ahand size squarethingcover in plastic connected toplastice looks like the pic it on the side of the blower
