Please make sure that the correct mode setting has been selected. Depending on model you will see the mode button has four little icons. A star/crystal, a teardrop, a sun (circle with lines out going) and a sort of triangle. You press this button until the correct icon appears on the display, it should be the sun icon.

Our AF-15 is working right. Not sure what to do. The fan kicks on and instantly shuts off and it will keep doing this until we have to turn the circuit breaker off. It is freezing in this house and we...


We need a bit more information:
So-- you are using the AC unit as a 'heat pump'-- trying to get HEAT from it-- correct?
And is it REALLY COLD OUTSIDE?- (Much below 35 deg. F-- Heat pumps become ery inefficiet as heaters-- since there is so little HEAT to squeeze from the Cold air outside! )

And how long has it been since the unit was CLEANED? For it could be a plugged heat exchaner.

Give us some more answers, and we'll see what suggestions might help next-

Thanks,

Fan doesnt work on heat cool ok


Often the fan will cycle on and off on the heat mode. A cold air prevention mode is often built into modern Ac units whereby the indoor fan wont turn on until the internal system pressure is up to a certain point and heat is available to pump into the room. If the system cant come up to pressure or temperature then possibly the system is low on gas. Place your hand on the large pipe leaving the outdoor unit, it should be HOT when the system is on heating mode and running. If not Hot, then it is low on gas.

LG split system cooler/ heater heater not working


This could be a problem with the interconnecting wiring or a control board problem with either the indoor or outdoor unit. I would have these issues looked out.
Hope this helps

No hot air


There could be a couple of problems going on. Your fuse on the heater up in the attic is popped.
Your glow ignition is broken.
Your spark ignitor is bad (if that is what you have)
GAs valve is bad.
Or the vent sensor is bad, meaning that the exhaust fumes are not going anywhere.
Now when you turn on the heater your condensiing unit outside should never turn on unless you are calling for AC. Now if the ac is not coming on there can be more problems.
Disconnect fuse is popped.
Wiring is wrong going to the heating board.
No wires for AC going to the thermostat

Heating problem with one split in a double split system


Either the board or capacitor have failed. If the motor is HOT the motor could also be the problem. in oder to tell if it is the board you will have to check to see if there is power coming fromthe board at the place where wires hook up. If power is there then it is either the motor or cap.

20 year old central a/c heater not working


Check your thermostat and mode selector setting, thermostat setting should be set at warmer and mode selector setting should be at low heat or hight this is applicable for manual unit.
If it is a remote control just set the remote to heat mode.
