Question about Heating & Cooling
Split level house with a thermostat for each of 3 levels. Highest and middle level heating is working. Lowest level does not provide heat. Repairman visited and tightened electrical connections to the lowest level and it worked for a few days.He had indicated that the lowest level thermostat was mis-calibrated and that we needed to turn it up to higher degree than it would generate. However, he did not seem anxious to replace the thermostat and said it should still work , but we would have to turn it to higher degree than it would actually provide. After a few days of working , the lowest level does not provide any heat.
You should have a trained a/c tech take a look at and adjust the bypass in the attic, it's letting too much air return back to unit not to zone.

Is this an electric or gass furnace - Eather of these can can have this problem its most recomendable that you call a seviceman .
in the case of electric furnace you may requier a new heat sequencer. And in the case of gass you may requier a new relay.

It sounds as if you you have a low charge of refrigerant, r22. When the unit comes on outside, the outdoor coils become the lowside, there is a low pressure switch that is tripping out contactor protecting the compressor.

Hi Radan, Did you get this problem solved? We have an Electrolux Kelvinator Split System and ours is doing exactly the same thing. I am struggling to find a solulution. Would be great if you can offer any advice.

One thing you can try is to remove cover, it just snaps in place.There are two plastic leveling posts at top two sides. You will need a small level commonly called a torpedo level to set on these leveling points.It should be very close to level,bubble in middle. If it's not look at base plate against wall and locate two lower mounting screws there will be a small slot where the screws go into wall to allow for slight adjustment.You will need a small screwdriver to back these two screws out a little maybe 1 turn.Adjust thermostat base so that level has bubble in middle and carefully tighten the screws,keeping t-stat held level. This should help some but it is not unusual for set temp. ont-stat to be off 3-5 degrees from thermometer reading. Hope this helps you.Thanks.
