Blower Turns off if ac unit comes on. No air coming through vents

I had a brown out so I turned off the air. The power came back on and I came home and turned on the air conditioning and the outside unit is working but the furnace doesn't blow the cold air into the house.. I have checked for frozen lines and there are none. I turn the air off and the fan to on and there is air coming out of the vents inside the house so I turned the air on and then the air quits coming out of the vents. Please help:)

This only could 1--2 things, a bad circuit board fan relay or bad thermostat. To check for bad thermostat, take off the front cover to reveal the 4-wire terminial and jump the red-wire (power)-cool,(yellow -y or blue)--- green--fan white-(heat)..........red to yellow-or y=cool. Thank-you-very-much!

The air it will not blow out of the vents. Only tried on AC


The humming coming from the blower is probably your blower not operating. It may be a number of things.if you turn you AUTO-ON setting at your t-stat to the ON position, it should operate your blower (indoor) only. If that does not bring the blower on its probably not your t-stat. Check all your breakers, both at the indoor unit(if equipped you should be able to see them without removing any panels), and at your breaker panel. If a breaker is tripped, reset it and then AUTO to ON again at the t-stat. If no luck it may be the blower motor or any component that connects to the motor. Call a tech.

I have a Trane XE1200 AC unit which emits a slight electrical burning smell when it turns on / cycles throughout the day. the smell is very similar to that of the furnace when it initially turns on during...


I would have a tech come out and check the voltage going into the fan relay and fan itself. The smell being as how it is coming through the vents in the house tells me that the problem has got to be at the blower or in the area at the blower fan which leads me to the possibilty that the smell could be the windings on the motor. This could be because the voltage may be to high. Good luck on repairs

AC unit outside turns on but no air blows through the vents


The first problem sounds like the wiring is wrong up at the heating unit not turning on the blower fan in the heater when you call for cooling. Most typical is either something has chewed the wires or the wires have been stripped b something else. The AC not cooling your house can be either it is low on freon or the system is to small for your house. Also check your filter and make sure that it is not blocked and everything is clean with the filter

Air conditioner not working


the outside condesor unit is not coming on for a number of possible reasons. First check your breakers for a tripped breaker, even if they appear on, turn the ac breakers off and then turn them back on. if after this, turn on the thermostat, outside you should here the contact switch on the condensor unit humming. if still no power, check for any breaks on your wires going in from the house, still nothing give a call back

My Blower Turns itself on when it is not supposed to.


If your indoor unit is located in the attic, you may be experiencing the result of a high temperature safety device (possibly too sensitive) that is responding to warm air drifting up the return air duct. The function of this device is to turn on the fan at a given set point and cool the unit back down. Have someone identify your limit rating and change the limit device with one rated the same or see if the maker of the unit has an upgrade/service bulletin on this fault.
