In my Liberty doublewide mobile , I have an Intertherm LP furnace and an after-market Unitary Products Group A/C unit . " Heat " mode works fine and the blower cycles with the burner . In " Cool " mode the blower does not operate and therefore the indoor " A " coil is coated with frost and of course no air movement . I've lived here 8 years and can't figure out what component is responsible for cycling the blower in " Cool " mode . I've replaced the blower motor and the " Fan Sw " # 626337 temperature - sensitive thermostat that turns the blower on and off in
" Heat " mode . Can you help... Please? Jack
