My 8 yr old Amana heat pump, model RHE48A2D with Honeywell progammable thermostat in heat mode has the blower running constantly. When there is a 6 to 8 degree differnce between room temp and thermostat setting compressor runs as it should, the closer it gets to thermostat setting, it will run about 30 seconds, blower continues to run until getting just cool air, about 5 minutes, compressor kicks back on for 30 sec., continues to do this, thermostat shows it has reached set temperature,
Hi, It sounds to me like what you are describing is, that when it is 6 to 8 or so degree difference then the stat says, unit operates as it is supposed to but then before it satisfies the t-stat, it shuts the compressor down long enough to start cool ... Air Conditioners
I have a Carrier Debonair 250 thermostat runs my AC and heater made by Carrier. it continues to run past the SET heat setting of 68. One day we were not home it continued to run until 99 when we stopped it and temperature was set to 68. When I leave it in AUTO mode (heat 68 and cool 70) it will run both heater and fan/ac continuously without any interruption. It did this for more than 4 days. Since then we are manually operating this. Is this my Thermostat that is bad or my system is bad. Please
Hi,\015\012The heat relay in your thermostat is hanging up.. then the heater overshoots and the thermostat turns on the A/C also...then you have them both running at the same time... right??\015\012Replace your thermostat and you will be ... Carrier Air Conditioners
The blower in my Ruud gas furnace won't shut off. It just runs and runs. The thermostat is set to "off" and the fan switch is set to "auto". We haven't used the furnace or AC the past few months since we haven't needed it, so it's been in the off position. Then yesterday out of nowhere the blower randomly fired up and hasn't turned off since. It just runs and runs until I kill it at the breaker. The thermostat is about two years old so it's fairly new. I replaced its batteries and that didn't
I'm not sure what setup your unit has but the fan relay sound like it is bad. If your blower connects to a circuit board then the board could be bad. Different units use different ways to control the fan. Some use a relay like I mentioned. Some use t ... Ruud UAKA037 Air Conditioner
Ihave an Intermatic mechanical timer model T104 that runs pool filter equipment. Had problems with the old timer and replaced it with a new timer - wired it exactly like the old timer - one wire at time so I was sure not to mix any wires. Turned it on and everything worked - set the off tripper and waited about 25 mins for it to shut off and it worked great. Set the timer for the on and off and it came on ok but didn't shut off. Have re set it and in came on and I was watching it when it was
Hi,\015\012No there is no difference in the T104 and the T104M the m just stands for mechanism only...\015\012\015\012So it would seems vey unlike ly that both poles would fail... so it seems that the internal part that moves the co ... Air Conditioners
Thermostat setting I just bought a new house and I have a heat pump-we live in North Carolina. The name on the thermostat is Braeburn and it is a multi-stage 2 heat/ l cool digital thermostat. We have it set at 68 and when the blower first comes on it blows warm air-however then it switches to cool air. And sometimes cool air comes out first. We have set both stages to 68 and it is in the heat mode. Should the 1st and 2nd setting be different?
What i would do is see if the outside unit is working at all. when you first turn it on the air was warm due to the fact that the temperature inside was cooler than the set point. when it get within 2 degrees ... Weather King 12AJA6001AH Air Conditioner
We just purchased a brand new Goodman 4 ton 15seer heat pump, model #AEPF4260TX5N4472#-- with a Honeywell thermostat controller,model#0836. The installer is having trouble with the fan not cutting off when it meets the set thermostat temperature. The fan keeps running, even if you unplug the green wire from the thermostat, or if you totally unplug the thermostat, the fan still runs. I am thinking that he has one of the wires wrong. HELP!
If you turn the power off and then back on does the fan stay running then. It is possible that the wiring is incorrect but it could also be a faulty fan relay or limit. If you disconnect the power when it is running and then turn it back on and the f ... Air Conditioners

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

I have a new Carrier HVAC system with a fancy EDGE thermostat. When I turn the system OFF at the thermostat, and set the fan to AUTO, hours later I will find that the fan is running and it's setting on the thermostat is now ON. How can I permanently turn off the fan when the system is off?

Air conditioning unit not running but fan keeps running even though thermostat is turned to off, auto, and temp set to highest position 90degrees. 3 amp fuse keeps blowing on the circuit board in the blower compartment. I replaced it 3 times then installed a new thermostat. no change. I can usually figure it out if I got a little input or direction. Any help would be deeply appreciated. I would much rather have a trained expert easily repair my hvac unit but I can only call the professionals in
If the fuse is blowing then this is generally indicative of a short in the low voltage wiring, isolate the wires on the thermostat and the unit ends, use an ohmmeter to verify that there is no path for continuity with no wires touching, if there is t ... Air Conditioners
Model(MC42B-1A) The unit stoped working. Now it will not come on. There is 240v at the outside unit. When the contactor is pushed in manualy it starts and runs untill released.

I have a new Dometic RV Air Conditioner Model 57915.751JO (13.5 BTU). It cools just fine but it only runs for 2-3 minutes, then shuts down for a few minutes, then recycles again. It should run until it reaches the temperature setting on the thermostat. It just keeps recycling. There is no visible power setting switch that I'm aware of.
This is a symptom of the system being low on freon. The system will have a low press switch, and as the the suction press drops the switch will brake and stop the compressor, then as the press rises it will start up again. Needs more freon, r134 I be ... Dometic Air Conditioners
I recently installed a new thermostat. The switch settings are not functioning properly. With the Heat/cool switch on heat and the fan switch on auto the fan works. With the fan switch set to run and the H/C switch off nothing runs.

I have a Ducane fits all 92 my lanlord installed,about 3 months ago.The thermostat is a new digital. The temp is set on 68,and if i go to 72 for example,the furnace starts and runs fine for about 3 to 5 minutes.The burner shuts off,the blower continues to run,And the buner tries to relight,and it fails to do so.The only way to get the furnace to run again and blow hot air is to shut the system off and restart.
Sounds like you are not proving flame to me. Could be a variety of things. I think it may be the board...but that is a guess from past history with Ducane ... Air Conditioners
I have a new home that is near to completion. Two heat pumps (zoned) are installed and both are now running - house is completely closed and is comfortably warm. Only the downstairs pump is being used at the present. The upstairs thermostat is turned off. The downstairs pump cycles every 26 seconds, that is, on for 26 and off for 26. This never changes. The ext temp is about 56 and the thermostat is set to 68. The pumps are both contractor grade Carrier 13SEER, 2 ton units, and the total

I have an Edgestar Portable Air Conditioner AP12000HS. The Air Conditioner works wonderful, however I can't get it to heat, I put the Mode Button on red which is supossed to put the heater on, it will run for a few minutes and then shut off and it does not take the chill out of the room I have the unit in, is there some kind if thermostat internally which can be set? The way it runs now does not do me any good as a heater.
The unit has a built in thermostat in the front control panel, this is what maintains the set temperature, it is very likely that this control is defective, all the controls for the unit are contained in the CCU (central control unit) ... Air Conditioners

Kenmore DX1400 central air unit when running turns on and off contiuosly and sometimes will not turn on at all for days? We have checked the breaker, of course no problem, checked the thermostat and it says it is working, all the settings are correct. Then a day or so later it will start to work again usually just before the Technicians calls to confirm the appointment.
