I have a heat pump with the unit under the house. We have noticed our power bill has increased. After crawling under the house I notice the drip pan is full and not draining through the pipe. So I unclogged it and it drained fine, but my next issue is, why would the return duct have about 3 gallons of water sitting inside the pipe making it sag. So what can I and need to do to fix this. I have been covering the ducts to cover the leak that I found but this water in the pipe has me baffled. Pleas


Hi, this sounds as though you just have a backed up condensation line that you opened up the drain, and you say it drained fine. As far as the return air duct having water in it, it is connected to the return side of the evaporator coil and it just o ... Air Conditioners

Always running I just bought this house with an existing Ruud system installed and have noticed that the air is ALWAYS running. It never pushes the heat past the set temp to make it turn itself off it just runs at the set temp forever. Needless to say this is a killer on the electric bill and I am seeing if I can fix it hear before having to call in someone to service it.

I have a Dometic Duo Therm rv Roof Air Conditioner Model# 59516.531.The fan is blowing and the compressor is kicking on but it is not blowing out cold air. Someone said it must be out of freon. Why would there be no freon? Can a technician add freon to this unit or do I have to change out the whole thing? please help!


These are a closed system.(meaning that there is no fill valves for recharging) But a heating & cooling technician can solder them on and re-charge the system. Only problem there is to get an estimate up front, and compare it to buying a new roof ... Dometic Rooftop RV Air Conditioner

PAID AN A/C COMPANY TO COME OUT AND FIX MY A/C. THE OUTSIDE COMPRESSOR WASN'T COMING ON. AFTER AN HOUR HE DECIDED IT WAS THE ''DEFROST BOARD'', AND SAID HE DIDN'T HAVE ONE ON HIS TRUCK TO REPAIR IT AT THE TIME.IF I GET THE NEW PART, IT DOSEN'T SEEM THAT HARD TO REPLACE, BUT I KNOW HOW THAT CAN GO SOMETIME. THE TOTAL REPAIR BILL WOULD BE $260. IS IT REALLY HARD TO REPLACE THE PART MYSELF? I DO REMODELING WORK, BUT NOT REAL FAMILIAR WITH A/C. IF SOMEONE COULD TELL ME THE BASIC STEPS PLEASE.


The defrost board isn't hard to replace. It just about matching up wire for wire on the unit. BUT and a big but.......if you do something wrong and burn the board up, then you have to buy another. At least this way, you know that he will put the p ... Air Conditioners

My 38CKCK24330 Unit stopped running, it will try and turn on every 10 or 15 mins you can here it outside buzz, I looked outside at the unit and the fan is not running. The system has power, the breaker switches are working, the furnace turns on fromt he attic. What do I need to trouble shoot, someone told me to check the switch on the unit by pressing it in to see if the fan will turn on once the button is pressed in. I did this but the fan did not turn on. Any help would be appreciated it, I

I just entered this question before but I would like to add to it. I was told by the super that there was freezing inside however I don't see it. Maybe I am looking in the wrong place, it is hard to see since the front does not come off. Would the freezing be in the front? I was told not to keep it on high so it would not freeze. I set it about 3-4 notches from the highest, and last night it cooled all night however, when the heat of the day started it stopped cooling. I was then told to put it

Have had ice and snow here in ATL. Today heat in Weather King RCBA 3765 GG17 would not come on. Checked Breakers, A/C breaker was tripped. Reset breaker, checked for ice in condenser (W/K 10PJA 3701), made sure I was getting 230 V to HVAC in attic, jumpered Y to G to see if blower would turn on, but it would not. Blew out condensate line and checked for ice in the inside unit coils. Acting like a limit or door switch is open, but I don't see any such switches. Anyone got any advice? Thank


Try R to G instead. The red is the 24v side. Greeen is the blower. You should also have 24v ac between r and c (brown or black) at the air handler. You can check at the condenser for power also. Turn the unit on at the thermostat and go outside to ... Weather King 10PJA2501AH Air Conditioner

Hello- I have a 1989 Fleetwood RV with a Coleman AC Unit on the roof and it just stoped working. I beleive it may be a fuse but I can not find it. I would like to start there by checking all fuses. Is the fuse inside the roof mounted unit? Can you help my friends? I'll be in the RV and not at the computer. Can you call me at 480 231-2900 right now? I would be grateful. Perhaps we can find the problem together. Edmund Pongratz

I have a roof air conditioner on my motorhome. It is leaking into my RV between the roof top and inside roof at the very front of the unit. I have pulled the upper cover and the metal cover for the evaperator. There is no water pooling anywhere, Dry as a bone. Lots of water pouring into my roof though. The Unit on roof has been sealed around the edges all the way to the top of the pan. I figured the condensation would fill up the pan then run over the edge onto the roof top. Somehow it is runnin

Went to a family dollar with a roof top unit and at the time could only check right above the drop ceiling, where there was a return and supply flex and a piece of square duct going through the roof and a novar control board mounted on the duct with it looked like 6 or 7 wires on it and 3 wires going to an alarm.. there was no power on the board and the fuse in the board was NOT blown.. i could only see that..i couldnt get to the roof.. have to wait till friday to come back with a tall enough la

I have a Thru-Wall Carrier 18000 btu Air Conditioning Unit Model KCA 183 P. This was installed in our mobile home in August 2007 but never used as there was only 30 amp service. The previous owner has either lost or missplaced the Operator's Manual, and as we have just now upgraded to 60 amp service, would like to use this unit. We can get it to run, but as it is digital we aren't sure what the icons represent, and how we should set it. We would love to be able to get the Operator's Manual

Purchased Goodman 5 ton unit in 2007. The problem we are having is: When you turn the unit on and set it at 76deg. the temp states on the controller it set at 81 deg in the house, BUT it would not cool enough to bring the house temp up to 78deg. the unit stayed on all evening, and remained at 86 deg without ever shutting off.... I know thta is going to hurt at bill time. Any help you can provide would be appreiated..... My email address is: [email protected]


Your system could have lost its refrigerant charge through a leak. Check for visual signs of oil at any soldered joints. This would indicate a leak at a point where some oil is visible. Also check for frost on the big line that returns to the outside ... Goodman Air Conditioners

Bought a used travel trailer, previous owner says the air conditioner works but you have to spin the shaft on the motor as someone inside turns the unit on. This entails someone going to the roof taking of the cover. Are there any fixes for this problem, besides buying a new rooftop unit?

My air conditioning unit stop working (outside unit). When I turn the unit I notice a buzzz sound comming from the unit. I have pressed the reset button on the unit to see it that would help but nothing happend.

The other day. my American standard air conditioning unit (Allegiance 10 model 7A0030A100A0) would not stop running. The furnace was not running, yet the air conditioning unit was on. I could see condensation on the line running to the furnace. The next day the unit would not even start running. I shut it down, tried it the next morning and the unit ran for about 30 sec and stopped. Could the capacitor need replacing?


Yes, that might be the problem but in this case you need a qualified technician to test system and find real cause of problem. ... Air Conditioners
