Having problems with your Air Conditioners ?
My unit is running but not cooling
Hi,\015\012 Probably not an easy fix. Sounds like its shutting down on Low pressure or High pressure. Could be condenser fan motor. The easiest thing it could be would be a run capacitor on the fan motor. They usually swell up and or leak oil when they go bad. You could check on that but make sure all the power to the unit is shut off before working on it. I would just call the manager or owner myself if I were you. I'm sure he is charging enough rent for him to cover such problems. Hope I have helped.\015\012kstfas

I have a carrier Modle No. 38YXA042300. I am getting an H5 error message on my Thermistat Control. I have run the Fan only mode and the fan in the air handler unit works fine. On the unit when I ingage the manual override, the condener unit and fan motor runs and cools. The unit will not run when I put the Thermidistat on Cool mode. Can you help me.

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.

1996 Coleman Model 7333C8876. Have 2 units on our Motor Home one day it was hot so I had both units running controlled by a Electronic Climate Control system. It got cool in the evening so I turned them off. The next day when i fired them both up on high the rear was fine. But the front will only cool on Low. The fan will not run on high and you can hear a slight noise coming from the unit. But the fan will not run on high.

Fedders Model No. A7U12W2A-A, 12000btu airconditioner. The unit has been cooling satisfactorily for two to three years. Today the unit was cooling and suddenly there were a couple of reasonably loud knocks and the compressor stopped cooling. The fan continues to run. In about five minutes the cooling comes back on. The compressor runs for abut four minutes and shuts down. Earlier today we had a power dip without losing all power.
Hi, the power dip when translated means low current actually affected the relay starter which is situated beside the compressor. Now the relay starter works and stop intermittently which is why the Compressor cools whenever it works and does not cool ... Fedders Air Conditioners

AC Out. Two year old house. Goodman A/C, two units one for upstairs. Cleaned coils of both outside unit, replaced filters, re-set breakers. Upstairs is cooling. Downstairs unit is running outside, not circulating air inside (inside temp 87). Vents inside are cool to touch, no air. Outside unit fan is pulling, but air exhaust is cool. Compressor ? Should air be circulating even if compressor not functioning. Is there anything in attic exchange that would affect downstairs circulation. Thanks.
Assuming that the 2 systems are isolated, that there isn't any cross over between the systems...It is normal for an air conditioner system, from window unit to central, to be able to circulate the air, even if not cooling. This is known ... Air Conditioners
I have a Duo Therm Quick Cool, model 59516331, mounted on a 2001 Dutchman. With the A/C on it cools great but the compressor does not kick out or cycle. The unit runs until it freezes and can't blow air. When I shut the unit off manually from the thermostat the compressor continues to run, the only way to shut it off is to shut the breaker off. I am wondering if it could be the thermostat? I have checked everything I can think of. Any advice for me?

Ac units in apt. is fully charged,but it blows cool to cold air and will constantly run all day with out shutting off. at night when it cools off outside it will run like its supposed to. the fan unit outside said bryant on it.

I have an older ac roof top unit (1988) its made by Coleman. When you first turn on the unit as long as it is cool, it will run for about five minuets on the low speed cycle (very cold), if you switch it to high cool it will run for about one to two minuets then it will trip the house breaker (20amps), not the couch breaker (30amps). I replaced the start cap, motor cap and another unnamed cap. The only things left in the system are a start relay and a thermal cut off switch which sits on top o

I have a Mitsubishi MS-09D wall mounted air conditioner. The cooling function does not seem to be cooling. The fan is running but the it seems to be recirculating the air only. The defrost light is red on the wall unit. I don't recall this light ever being on before. Could a button or combination of buttons on the remote unit have been bumped somehow?

Good day! I am running my Carrier A/C Model 38EYG and it is running fine...the outside unit is running fine and the air coming out of the ceiling vents is cool. However, the inside unit (the one in the closet) is very hot. When I walked by the closet it felt like I was walking by an oven. I checked the temperature with my handy temp gauge and it was reading 120 degrees near the top of the unit...is this normal??
No its not normal. Check and make sure there is no flame inside the furnace. If not , turn the pilot light off it is a gas furnace and see if this makes a difference. good day to you too. ... Air Conditioners
Friedrich YM18 230 volt heat pump. The unit has heated and cooled well for about 5 years. Just started heating mode recently and the unit no longer heats. Fan runs OK. Was able to get the heat strip to run for a few minutes (smelled the dust accumulated over the summer burning off). Now, no heating whatsoever. When in the "Money Saver" mode, nothing happens. Fan will not come on and unit will not heat. With "Money Saver" mode off, the fan runs.

My unit is running but not blowing cool air. I went outside and the condenor fan was not moving. Took a stick and shoved a blade and the fan started moving but the air is still not cool inside. I did notice the air coming through the unit outside after fan was blowing was cooler than my 2nd a/c unit that was working fine. I wondered if the entire unit was frozen. I turned off unit at thermostat and figured I would see what happens tomorrow
Sometimes on new units it is common for the fan to not start until you give it a push. Did you happen to hear if the compressor was operating? If the unit was froze-up the Insulated Suction line would also be iced over as well. If it wasn`t it is mor ... Carrier 38CKC024 Air Conditioner

This is for a Friedrich QStar SQ06J10 AC unit - When switch is normally shifted to the 'cool' position ('on' mode), it seems to not complete the circuit. Jiggling or pressing hard on the switch will make the unit run, but one has to hold the switch. Can a DIY-approach fix the connection, so the unit will run as expected? or does the switch panel need to be replaced? Relatedly, might it be 'better' to simply swap out this unit for a newer, possibly more-efficient unit?
