Heating problem hello! My air conditioner stopped to heat. (there is a around 8 degrees C, outside and 16 degrees inside). It worked just fine, and now, when I switched to heating mode, there was nothing. the defrost LED ond the inside unit is switched on, but air is not comming from the unit. Cooling mode works fine. If you could please help me finding the solution for my problem. Thanks in advance. RAdan GE AIR CONDITIONER SPLIT SYSTEM WON'T WORK ON HEAT CYCLE Seems to work ok doing everything else?

Are you trying to heat with your air conditioner?-- here are a few points to keep in mind:

Remember, for an air conditioner to PUT OUT HEAT-- (as HEAT PUMP) -- there has to be some HEAT outdoors, to make the process work...
So-- ask yourself-- How cold is it outside?
How cold was it outside, the last time that my AC worked good as a heat pump?


Possibly the coil outside is all frosted up?--

Shutting it off, and letting the outside coil defrost might help-- but-- the basic law of physics still stands: To get heat inside-- there has to be some heat outside! (Likely your unit won't give you much heat inside, when it is below 50 -- or for sure-- below 40 degrees outside!)

Give us a few temperature readings- inside and out, and then gives us clues as to what is running, and what is not-- maybe we can trouble shoot deeper. Is the compressor running?-- does it sound like it is actually working-- or just running-- sort of like 'running but not really WORKING'?

Let us know--

Heat pumps are the same as an A/C unit only it works in reverse. Instead of blowing cold air inside and hot air outside it blows hot air inside and cold air outside. The heat being blown inside is extracted form the cold air outside. Its called Latent heat Latin for hidden. Believe it or not even though its 20 degrees outside there is still heat in the air. Example if you want to drop the temperature of a freezer from 20 to 10 degrees you have to remove heat .I know your getting unusal weather and that is the problem. Heat pumps can only work no lower then around 20 degrees outside.Heat pumps are never used above the freeze line. With your unusal temperatures thats basically where you are now. Ride it out. When your temps rise a little your be fine. Im in Chicago.

Hello my name is Heath it will be my pleasure to assist you. If you are talking about r-22 with an outside temperature of 75-80 degress farenheit it should be running between 62-68 on the low side and 200-225 on the high side but there are varibles to take into account like the air flow across the inside coil or a dirty evaporater just things to take into account these pressures are approximate if there are close it should be fine.

A heat pump starts losing efficiency below 30F or so. The aux. heat helps the heat pump keep up with heat demand. The Aux heat can be electric heat strips or another type of heat. Check to make sure you have power to whatever type of aux heat you have (breaker not tripped, no overloads tripped). If it is electric heat check the heat strips to make sure they haven't burnt in to. Hope this helps.

Bad thermostat, improper wiring or bad circuit board in furnace. Turn off the disconnect outside.

Your outside unit is not defrosting. You need to call a service tech to check it out. Defrost board sensor or low on gas. Also you amy have an outside tstat that is not working correctly. Rus

I don't have the book for this particular unit but, check the sequencers that control the electric heat mode, as the regulator heat pump works good. The part may have a time or temperature delay that is too long for you. Also if it has a remote thermostat, check the heat anticipate setting. You will have to check the installation manuel, but its usually .6 to .8, but I don't think that is the problem.

The LG>LW5200ER AC is not listed as a heat providing unit. Click on link and this will give you the spec's
