Question about Heating & Cooling
I am cold. I am trying to get heat flowing through the house but it isnt working. I go to the thermostat and just put it to on and the system in the attic turns on and blows air. I turn it to heat and dont get any warm air. I know the outside unit isnt turning on and was told it should. I dont remember all these years the outside unit turning on. Of course I try to turn on the a/c and the outside unit still doesnt turn on. What do I need to look for. I have a Tappan 4ton split system if that info helps. Thanks.
If im correct, you may have a heat pump system. this unit, when set to heat, will and, should run in unison. if the outside isn't running, its probably a compressor issue. if you don't have a heat pump, you may be experiencing main unit malfunction. some units of this nature have supplementary heating for a back up. it should say this on the indoor thermostat on the wall. set the supplementary dial for now. it should heat until you get this repaired.

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
