Having problems with your Air Conditioners ?
++HAIER 3125. Fan shuts off.
Hi! there it seems that your control circuit board is activating default set up or abnormal set up after recieving on control circuit board when you shut off the unit, there's a short circuit behind on holding relay when deactivation process is done, the holding relay should be cutting your entire source connection on compressor terminal when you shut off the unit, in this case try to isolate checking supply voltage behind relay and the supply source terminal of your relay, .try to check on this to your manual circuit diagram to lessen the complication of trouble shooting just focus on relay circiut,replace relay if defective.this is a hard job and should be done by qualified a/c technician. have a nice day regard and thank's a lot

I have a Coleman Presidential 7670 furnace in a mobile home. customer said it came on a couple of times by itself. I ran new wire, fan won,t shut off. Replaced fan switch, fan still won't shut off. Replaced t-stat, same problem. This is an older unit and has no board it has a fan switch a low limit switch, i,m guessing the other is a high limit and a fan relay. I have no schematic and am very frustrated can anyone help me please. Thanks. Brian from california
Brian, it sounds as if possibly the fan relay is stuck however, if the fan will not shut off I would suggest the following, Follow the wires from the fan to the relay on the relay disconnect the fan wire there and see if the fan shuts down if so t ... Air Conditioners
I have a Dometic rooftop Air conditioner in my RV When I turn it to low medium or high the fan run the same speed and when I turn it to AC it will run for about 5 min then the fan will shut off but the compressor keeps running I turn it off for a min or so and everythings comes back on. Turn it to the fan only side and the fan will run for 5 min then shut off a min later it comes back on then back off and on in fan only side.
Bad fan motor I suspect The windings are bad causing the motor to over heat sending the motor into thermal overload. would suggest the replacement of motor. Good Luck on repairs\015\012\015\012Dave ... Dometic Rooftop RV Air Conditioner

Turned on the furnace last evening to warm things up. When reaching the auto, shut off temperature, the fire/heat shut off OK..but not the fan. Had to shut the power off in order to shut off the fan. What might I do to fix this problem? Is there a reset button (I didnot see one)? Thanks for any help!
Turn the syestem to off-no heat or cool and the fan to auto, turn the power back on, if the fan comes on you probably have a bad fan limit switch. ... 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

Rbhc-17j11sfa blower fan refuses to shut off in heating mode when heating is not required and fan is set on "Fan Auto." But it shuts off in cooling. It's a new Honeywell programmable thermostat. Wonder why. Many thanks.

The electricity went off in our neighborhood yesterday. It came back on. I do not run my central air this time of year so the air conditioner is in off position. My fan is on auto but this usually means it is also in off position. When the electricity came back on yesterday the fan came on (not the air conditioner) and is continually running. I cannot get this darn thing to shut off. I have looked on the internet and made serveral attempts to get this fan shut off. I do not want to pay for

When the AC fan shuts off, the compressor appears to be stuck. It continues to make a humming sound as though it is running. If I remove power and return power it hums momentarily and then shuts off. Is it OK to allow it to "hum"? I constantly kill the power when the fan shuts off in fear of harming the motor or compressor.
Yes, not good for compressor to stay on after being shut off, and hitting the breaker to stop it is a good idea. Sounds like you have a faulty/sticky relay. Not an expensive part, and shouldn't take any longer than 1/2 hr to change. Have a technician ... Dometic Rooftop RV Air Conditioner
My fan limit switch will not shut the fan off in heating (gas). The dial on the limit switch rotates till the shut off point then sticks. I have to turn it manually to shut it off.
Make sure nothing is bent and causing added pressure to keep it sticking.\015\012\015\012You will likely need to replace the limit switch.\015\012\015\012I don't know your model, but its probably 2 wires, 2 or 4 screws and run ... Air Conditioners

I have a Haier HWR05XC7 that will NOT work. The compressor turns on, but the fan won't work. The fan moves freely because I tried moving it with a screwdriver, but when I turn the unit on, the compressor kicks on, but no fan. I have been fighting with this thing for weeks and am about to chuck it out of the window. Also, the red error light stays on and there is nothing in the manual on how to troubleshoot it (other than making sure it is turned on and plugged in!). No support from Haier or Circ

My Rheem Corsaire furnace is short-cycling. It ignites, the burners stay lit the fans run for a while then the burner shuts off, the fans run until the cooling oft temp is reached then shut off. Right away the furnace starts right back up. It does this until it reaches the temp the thermostat is calling for. I had a problem with the flame sensor last year, but then the burner would light and then go right out.
Try blowing air thru the pilot tube. You may have a spider web in the burner tube. ... Air Conditioners

I turn on the Central A/C unit with the thermostat. The attic fan unit goes on and the system cools the house. When the system shuts down the fan unit shuts off but the outside compressor keeps running. The only way the outside compressor goes now off is when I flip the 240 switch on the main box. This just started. Is it a thermostat problem? Thanks.
Could be a thermostat problem but even more likely the contactor on the unit outside is stuck. In order to change this part you will have to get in to the outdoor unit. The contactor is the automatic switch that the thermostat energizes when the t ... Air Conditioners
The blower fan does not shut off when it reaches the set temperature. Compressor shuts off but fan continues to run making the air inside very humid. Temperature is getting cold.

Heat would not come on and fan would not cut off even when thermostat was set to off. Took off the outside panel of the unit and red light was blinking 7 times - rollout switch fault. Since fan would not shut off, took out the disconnect to shut off system. What does this mean?
This means that the rollout switch was tripped by a flame coming from burners. could be a plugged fue or bad inducer motor, or a bad rollout switch. the fan will not shut off as a safety feature it keeps running incase the heat exchanger is to hot to ...

I have a new Salem travel trailer with Dometic products. Everything appears to work fine, but when I run my furnace and it turns on, my fan blows from my AC unit. I have owned 2 other RV's but have not had this problem. When the furnace shuts off due to temperature being met, my fan continues to blow and does not shut off. Does this sound like there is something wired incorrectly?
