The first thing that needs to be checked before more parts get damaged is the secondary or control voltage from the transformer. with the system off this should read 25 to 27 volts a.c. on average. low voltage has several possible causes, if you do not have a digital electrical meter and the ability to use it i would suggest a contractor be called. Chattering of controls is an indication of a problem and will create other problems if not corrected

Ruud uhqa sill runs when i turn off t stat contactor test good and is not stuckhit breaker and back on and fan stops running goes on when t stat is turned on stays on till i trip breaker again i think it...

Your sentence is hard to understand because there is no punctuation. But, I think you are saying that the Outside unit is still running when the inside unit is off and the Thermostat indicates it should be off. If so, you have a stuck relay outside in the compressor/condenser unit. This is common. The contacts get hot and fuse themselves together. You will have to remove the cover on the unit outside to expose the relay. MAKE SURE THE BREAKER IS OFF. If you house is to code there will be a disconnect box on the wall just above the AC unit outside. PULL THE DISCONNECT> then use a flat head screw driver and slight pry the contacts apart. If they are fused very tight you may need to replace the relay. If they break free put every thing back together and you're done. If you this happens again soon you will need to replace relay.

something is heating up it could be the ignition relay or a bad ignition switch. relay can over heat and stop working this would take some time to cool down again, ignition can do the same some times you can feel the heat on the key when removed.

I have inrertherm air condition with heatstreeps. model p3ra-048k.the blower and heat is "on"when mainbracker is "on" and thermostat wires are not connected

It sounds like a stuck Heat Sequencer (aka Heat Relay). The heat sequencer is wired so to run the blower and the heat strips simutaneously. If the Heat Sequencer contacts "stick" closed, the heat and fan will run non-stop as long as the main supply voltage is fed to the unit. It will need to be replaced. When you replace it, you will want to use some masking tape to mark every wire with a different code and write down where each wire was attached. This will save you alot of frustration later. If you have a cell phone with a camera, you can take a picture with the marked wires still on the relay. I'm including a link to a video that is showing different types of heating sequencers/relays that might help you to identify and troubleshoot your part.

I hope you found this information helpful to you. Good Luck in your endeavor! :-)

Coleman model 296OC666 vent blower will not cycle off. Don't know what to check. Replaced the heating relay 2 yrs ago. Don't know if it controls the vent fan and being only 2 yrs old and all other systems...

Hi, being that this is a newer unit, you will need to look at the fan control, or high limit switch.They will stick on at times and the indoor fan will continue to run. Being a Coleman furnace, in behind the circuit board, you should have a fan switch that has a manual reset on it. Try to locate this and push the button to reset, and fan will cycle down.You may have to do some searching to find it, and you can also look at the schematic to point you to it.Please keep me informed and I will work on helping you solve this. Let me know. Sincerely,

RUUD heat pump system does not cool properly.

With a heat pump system there are always going to be a back up heat strip inside the Air Handler.

If you detect a faint humming in the Condenser call your local service company and ask them to come and replace your capacitor in the condenser. The humming is from the contactor engaging but not being able to start the compressor due to not having the required Microfarads to start it.

Let me know if this helps

Themostat problem no power

Your R terminal in your air-handler is the 24v power that goes to the tstat. Look at the air-handler and match the color wire. ALL tstats have a power wire going to them. If you aren't getting power, you probably have a break somewhere in the wiring close to the thermostat you are replacing.
