My coleman Mach Rv air conditioner with built in heat strip keeps tripping it's internal circuit breaker when running for any length of time. Just replaced heat strip with new one experienced same issue. I ended up with the fan continuing to run but only cold air comes out of the vents! When I removed the old unit and reset the circuit breaker it too worked again. Have no idea what is causing this to happen. The airconditing part of unit works just fine??? HELP! Ron
There should be an overload protection device in series with the low voltage wiring(t-stat wiring) Is it resting on the heat strip or too close to it? It is a saftey device to shut off the heat strips if the fan quits or a fire in the heat strip sec ... Coleman Mach III Air Conditioner

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.

Bryant air conditioner - outside unit will not run - before it quit running, air temperature in house rose from 65 degrees to 75 degrees.

Have a Grand Aire Central Air and Heating unit a/heat pump...has been working fine. Switched it over to heat and nothing came on. Switched it back over to air, which was working and still nothing came on. Switched fan from ''auto'' to ''on'' and the fan will not come on. Used a screwdriver to push the contact in and everything runs (air and heat) as long as I am holding the contact in. Changed the t-stat, still the same problem. I really don't have the finances to call a pro in, any advice will

I hope this is help full cheers andrew
My gut says that this is evidence of a bad control board(circuit board). As usual, double check that your batteries are good in the thermostat. I have seen some weird things happen when the batteries are low. This one may be a job for your local con ... Sharp Air Conditioners
I have an LG mini split ac / heat pump system ( LAN096 ) that is only 4 months old was working great in all ways until suddenly it quit heating. I am sure it happened quickly because I was nearby when very warm air changed to cool ( unheated ) and hasn't heated since. When I shut it down and restart it the indoor fan runs right away, which is not normal and the outdoor unit will run for a minute or so then shut down and stay off. The indoor fan will continue to spin as though it is set in a 'fan

I'm having a problem with my heating and air system, my heat only works on emergency heat ( and run 24/7) if i turn it to regular heat it only blows cold air. i dont think my outside unit fan is turning( i could be wrong about this one) how can i fix this problem so i dont have to run my emergency heat all the time
If your Heatpump's fan isn't running but your compressor is, your fan motor is out. If nothings happening at all ensure your getting power to heatpump (ex: breaker tripped, fuses blown on outside power switch, or fuses blown in breaker box?) ... Air Conditioners

Air Conditioning I have a ruud system with the air conditioner outside and the air handler upstairs in the attic. My systems appears to be running, and I can feel cold air at the vents, but I can barely feel it. Like there is no flow. The fan outside is running and the unit in the attic is running. I have no clue what the problem is. The large coil coming from the heat pump outside is cold and has condensation on it. It also seems to have a little ice. It has been extremely hot here in Ge
Open the access panel on the air handler in the attic and take a look at the evaporator coil. If you have no airflow, and you just changed the air filter, then you probably have a buildup of airborne crud on the coil that's blocking airflow. \015\01 ... Ruud UAKA030 Air Conditioner

No heat We had the mini split installed and have not needed the air conditioner yet. But now that I want the heat on, I can't get any. The indoor unit lights up and the fan comes on but only blows cold air. I have checked everything I dare to, and noticed that the outside unit doesn't seem to be running. I am reluctant to call the guy who installed it because he was not a happy guy to do it in the first place. But he was the builders choice. Any suggestions of things to check into myself?

I have a rheem electric furnace with 2 speed fan, seems like the fan runs full bore when its on, even when i just cycle the blower control to ''on'' and its supposed to run at reduced speed. I have to experience with central heating and air, was wondering if it would be the circuit card with the dip switches. Unit was installed in 2003 with a heat pump.
If it is a variable speed blower most likely the dip switch settings. Check the installation manual to see how to slow it down. ... Air Conditioners
I recently had a new outdoor unit installed on my central heat and air conditioning sytem. I have had the installer out 3 times and the system still does not operate correctly. Sometimes when it cycles (every other time or every third time) the unit does not blow cold air. Sometimes the unit comes on not blowing cold air and the compressor fan is running but not the compressor. Sometimes after 15 minutes of this the compressor will come on. What is the problem.
It sounds like the compressor needs starting components installed on it. All a/c units have a run capacitor for the compressor and another one for the condenser fan motor. These motors use these capacitors all the time when the motor is running. H ... Air Conditioners
I have a Coleman Evcon gas furnace model# DGAT095ADA last year I replaced the T-O-D #60T82 - 313675 fan switch and works fine. This year the unit started fine, but slowly started taking longer & longer to heat up, then finally not heating up enough to trip fan switch. Manually tripping fan switch resulted in some warm air through system, but not enough to heat a house. Gas comes on and is blue what would be my next course of action ?

I have 2 kickboard heaters in the baseboards under the cupboards in the kitchen (Smith SS7's). They are run off the hot water central heating circuit. The fan in each unit is supposed to click on to blow hot air from the heat exchanger when the temperature falls. Both units have stopped working - when one stopped the other worked intermittently for a few weeks but now this does not come on either. I have bled both units and if I keep doing this then eventually hot water reaches both but the flo

Hello , this is Bobby and I have a Coleman Mach rooftop air conditioning unit Model # 8335B8964 when I turn on the unit ,it throws the circuit breaker . I have replaced the starting capacitor and the running capacitor for the compressor, the fan runs ok.Is there a circuit board for this particular unit?
Here's a link to a service manual, with step by step tests to determine whats wrong. I'm thinking compressor shot, but this should confirm, and or help you determine for yourself. Be careful with those capacitors eh !! Read warning in service manual. ... Coleman Mach 15 Air Conditioner

RV ac fan runs backwards (blows out air on top of RV.) Runs correctly sometimes but after it satisfies and clicks off when it kicks back on, it runs backwards. The only thing that will turn it back around is to turn off unit and wait for around 30 minutes and turn back on. (won't reverse motion very quickly) Spoke to Coleman expert and was told it is the fan capacitor. Need instructions to identify and change the capacitor. Would like to fix myself since this will be the 3rd time to have it i

Have Coleman-Evcon heat pump system. Model DRHS0421CB. Condensing unit has intermittent no run condition. I replaced the contactor, as it was a few years old. I eliminated the thermostat from the equation by twisting together the RYO wires at the thermostat sub panel. This makes the air handler run and MOST of the time also makes the condensing unit come on as well. When it does run together, it cools great. Suction and discharge pressures are normal. The float switch is ok and no water prese

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.
