Hi, there is a Ductless LG Model # LA180CP that has freez up problem. Sometimes it freez up after 3 days working and some times after couple of hours working. Freez up start from indoor unit. Average of super heat is 10, but it is changing all time between 6-15. suction line Temp 45F, Discharge 53F, On Gage 35F, Supply Air Temp 8.2C and Return Air Temp is 22C. What do you think about this issue? THanks
What refig and where are the pressures. freeze up is always low charge or lack of air flow and always occurs at the evap. Once it starts and you loose surface area you have to defrost manually ... Air Conditioners

This is a heating and cooling through the wall heat pump. It works normally when heating is selected - the heat pump runs and both speeds of the fan blow warm air. But nothing runs when cooling is selected. In other words the unit works normally when "High Heat" or "Low Heat" is selected but nothing runs when "High Cool", "Low Cool" or "Fan Only" is selected. The position of the Fan Cycle Switch has no effect - behavior of the unit is the same in both positions of the Fan Cycle Switch.

Central heat pump unit isnt keeping house warm and runs all night long - low temp has been in teens last few nights - noticed the outside unit is making a constant noise like whump-whump-whump - is it low on freon? should i switch it over to emergency heat only? any ideas what might be wrong?
Hi,Is it a Compressor that is making Noise? If yes, this is a Bad News. More often you need to Replace the Compressor.Usually when it comes to Warm air, usually that shows that AC is low on Freon.On Both Cases, yo ... Air Conditioners
Reversing valve Model: PHJ030-1A Seral: 9705062008 The reversing valve is not reversing to heat. I found a small hole at the condenser coil, with oil residue around the "U" shape joint. When the heat stop, the condenser froze up. I think the a/c part will continue to cool with low pressure. Could low freon keep the reversing valve from switching. Reversing valve need more pressure to work. I check coil, the ohms is 17.6, and I do have 24 volts going to the coil, but I did not check it in cool fo

I have a Lennox model CB19-51-1P air handling unit with HP19-511-1P compressor heat pump unit. I just turned the heat on for the first time this season. And I am getting low heat volume.

I am trouble shooting a Bryant Hi-bred system that uses an air cooled heat pump with high efficiency gas furnace for backup and low ambient operation. How does the system decide whether to use the air cooled heat pump or the gas fired high efficiency furnace. It appears to be outdoor air temperature related, but I can't find the setpoint for it. The main zone Bryant thermostat appears to control the system, but it doesn't always bring the backup heat if the heat pump doesn't function.

Heat... On low or high heat, the unit only heats for a few minutes then blows only cold air even with the temp turned all the way to heat. The status light on the board shows ok. Any ideas what to look for?

Fugitsu ART45LUAK ducted airconditioning. To heat the house I set the fan low, heat manual and thermostat 24C, the temperature keeps creaping up to 27C. The you can hear the thermostat being reached but the heat comes on agin, then agin till its really hot. Same thing happens when using the cooling setting, but in opposing temp ie set to 24 will drop to 20. If the select temp and fan is set to auto, it will heat up too much and then will then auto cool down too much like its fighting itself.

Amana PTH153B35AK This unit is less than 30 days old, heats fine cools fine, but when i have it in heat mode,set @ 70 or so, as soon as the room heats up, the unit will cycle into a/c mode and blow super cold air for about 5 minutes than return to heating.

I have a Tempstar model NFCP3600A1 (style # FCP3600A) ICP Heat Pump. Starting last week, the unit kept heating well over the set temperature. I swapped out the thermostat thinking it went bad, but it still continued heating and the "off" wouldn't work at the new thermostat either. Next, I checked for shorts in the thermostat wires and they seemed OK. I then replaced the TI 26FC-2 circuit board. Once the unit heated the house to the set temp, it continued running up to 75 degrees. "Off" and lowe

Goodman heat pump model CPKJ421B. Tripped breaker for outside unit two weeks ago. Reset breaker, tripped again today. Unit won't run now. Did some basic checks and found that the 28 vac from the inside unit was not going through the low pressure switch to pull in the 220 vac contacter for the compressor. Possibly either the refrigerant is low or the low pressure switch is bad. Could a faulty switch, maybe losing and regaining contact quickly, trip the breaker? Could the refrigerant, just before

I first checked the contactor and it looks fine, the inside thermostat had low battery voltage...replaced batteries but still not working? Any help? Thanks
Because the outdoor unit works in cooling, it sounds as though the contactor and other components outside are working correctly. The problem sounds as though it might be somewhere in your thermostat. Has the thermostat been replaced recently? If so, ... Goodman CKL60AR60 Air Conditioner

We have this air conditioner in our sunroom. From the beginning, the temperature set is not maintained. When the unit is set to cool, no matter how high a temperature I select, the unit cuts on approximately every 10-15 minutes, and cools the room to about 66 degrees. When set to heat in the winter, no matter how low a temperature I select, the heat cuts on about every 10-15 minutes, and the room will heat to a much higher temperature than selected.
