Hi,The fan running constant and the unit not firing is usually an indication that the high limit reset has tripped. And yes... these furnaces will run a cooler air... that is one way they get better efficiency...Also the ... Coleman Air Conditioners

I have a Nordyne Intertherm split system Model MMHA-056ABHR-01. The blower starts and stops or oscilates when trying to heat. The burner ignites fine and the fan will run fine when put on continuous. But when the thermostat is set to auto and calls for heat the blower starts then stops.

My LG LST244M split unit will run for a couple of minutes, then the condensor fan will stop and the condens will heat up and because of that the compressor will stop, why would the condensor fan stop?


Couple of things to check. 1st the capacitor for the fan may be going bad in which case the capasitor will need to be changed. 2nd. the windings on the motor may be going bad. The windings, if they are bad, swell putting pressure on the motor causi ... LG Air Conditioners

I have a Dometic 15,000 btu, ducted air conditioner in my 30 ft fifth wheel. It seems like the unit has never cooled very efficiently. Dealer has checked out. I noticed yesterday, outside air over 100 degrees, that the air conditioner would put out good flow of cool air, but once in a while compressor would stop running even though not close to thermo setting. Fan would continue running. Any suggestions?


Not sure what the pressure sensor should ohm at but i would suspect a faulty sensor if everything else checks out. Its very common for these sensors to exhibit issues when they get hot. Also you may have a filter in the system that may be restricte ... Dometic Rooftop RV Air Conditioner

I have a 2 year old Duo Therm 15,000 btu Heat Pump AC unit in my RV. The compresser will not come on or even try, in either cool or heat mode, the fans runs in either auto or on position.

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 a Arcoaire Gas Furnace (Model# GNJ100N12A1), that will not fire up. It has a White Rogers Digital Stat. First the Stat seems to be faulty, since it reads 70plus in a house that has a temp of 30 or below. I can adjust the Stat and the blower motor will run. The rollouts (3) were reset; the inducer fan would run; then the unit would cycle and shut off. Now the inducer won't run. The ignitor is good, but would never glow. A friend tested the current coming from the Stat, and found 24

My indoor unit on my heat pump will not shut off. The electric heat keeps running, and the fan keeps running. It only happens when it is really cold, like 25deg or below, above that and it functions fine. The outdoor unit shuts off, but the indoor stays running. I do HVAC work, but I have never seen a problem like this. I have switched the stat out, and its just so strange. I figured the relay may be stuck, but if I turn the stat off, it turns off shortly after which tells me it may not be the c

3 new Coleman 47073-879 ac units don't shutoff cleanly. 2 have heat pumps and they change fan speed quickly when starting and stopping.

I noticed some straining noise coming from my a/c unit today.

Then the fans kicks back on, the the process repeats itself every couple of minutes. Meanwhile no cold air is being produced inside the house. Any ideas?
