Microwave turning on Central Air!!?
Recently replaced the microwave over the stove c/w hood fan. Fan comes on every time microwave is turned on and, if thermostat setting is below ambient temp, central air kicks in. Can anyone explain to me the mechanism that is happening here. As far as I can tell, the microwave is plugged into an outlet, so no wiring associated with thermostat. Is there a trigger in the ventilation baffle for the microwave that automatically kicks in the vent fan which is then triggering the A/C unit? I'm a DIY rookie, so appreciate any explanation...cheers,
