no warm air -wall heater

7 posts in this topic

   I had my  in-the-wall  combinination heater - air conditioner  switched off for about 3 days recently,   then the  outside temp. dipped to 56 degrees, so early one morning  I pressed the heat button   which caused the fan to come on but no  warm air will come out of the vent.    I turned the thermostat to "warmer" but still no warm air will come out of the vent.   It does a great job of blowing tepid, room temperature air out of the vent.  This morning was 59 degrees, and still have the same problem, no warm air.   Any suggestions?   Should I call HVAC guy now  (while it is rather warm outside)   or wait until  colder weather ? 

Will the HVAC guy be able to properly diagnose since the outside temp is rather warm now ?

Need appliance parts? Call 877-803-7957 now!

is the unit electric heat or heat pump? electric heat could be an open t-stat or burnt off wire. heat pump ? try running a/c 15-20 mins- then switch to heat.

electric heat -then the heat selector switch may be at fault or element or high limit or broken connection. is the room temperature control builtin or remote?  is this unit push button controls? if so rock buttons between heat/cool... heat switch may not be fully engaging when pushed.  short of opening up the unit I would call for service

    The room temperature control is built-in     (not remote),    with push button controls.   There are 4 push buttons.......  Off,    Fan Only,     Cool,   and    Heat.         Beside the 4 push buttons is a  round  dial,   turn clockwise for "cooler"   or   counterclockwise for  "warmer".   

    I rocked the buttons between  heat and cool,   and  that did not fix the problem.

:dude: With that guy being almost 30 yrs old, I'll bet I know what the HVAC guy is gonna tell you. Not sure about your area, but around me HVAC companies don't work on those, the appliance guys do. Ask if they work on PTAC (Packaged terminal a/c) units.
