    Had allready replaced reversing valve and blower relay. They came back and rechecked the refrigerant and said it was fine, the clicking doesn't start when heat pump first starts it takes awhile before it starts clicking. I wonder about the blower relay, I don't have a part number for it, and can't find anywhere that can give me the original part number. Is there any way you can get me the part number for the blower relay. Ruud model # UPND-030-J Serial # 4508 F3191 1033 MFD. 08/91

I can tell you exaclty whats wrong . and it sounds like multipart problems. you have an old RUUD heat pump and its reversing vavle is stuck. without that valve opening it will contantly try to run in refrigerant mode to make heat. and here its 26 degrees, het pumps are only made to be effiient in over 34 degrees and that why your electric heaters in the blower section in an in a closit of unit
continously running up you eectric bill big time. cuses for the reversing valve to stick are sitting along time when it was low on refrigernt. or ust plain shut depending on its age. that cicking is the relay trying to open or close the reversing valve swict to make pressure again. any local guy an fix that one. theyre are kits called hard start kits that they hook up to them that shoot an extra zap of jiuse in it to try to free it up if its not totally lockd up being though that you still hear the relays pulling in and out thats good you may have just caught it in time.

now here is a quick test and possible cure but only if you what your doing turn both units off take off the top cover of the old rudd and get a small hammer not a sledgehammer and rap and tap all around the reversing valve. it will be a cylindrical tube black usually have sets of copper or brass tubings going in the 2 sides of this so dont hit itthat hard it gets dents it and is ruined. look for oil spots which uually means the refrigerant leaked out , and its seized up for good. they try spinning around the big out door fan door fan some. you may have to rock it back and forth Till it braks lose but dont put super human efort int it,

than put it all bak together making sure you connected wires back up right. go in and have you wife eithe watch it or you do it and switch the breker on and off about 8 times to trying to get the cnnectors switches to stay in and if your brave take a well insulated screw driver and hold them in for 2-4 miuntes to force it to work. if that doesnt do it call your local repairman and tell him you need a hard startkit only much safer, the cost about 40$ but you labor will be high if he is sent alone so may you can help im out and lessen your bill if the valve cant be made to work again. you may want start looking for prices with that model and serial number and d shut that electric heater off some one to replace it . I hope I helped you out some no charge ( I dont have my Pay Pal acct. set up yet ) good luck tom.

Coleman Evcon furnace blower runs w/ no call for heat. Temp is 5+ degrees above thermostat setting. (Programmable tstat)


When you say door are you referring to the front door or the furnace door? If the unit kicks on AND off by itself I would say it's in the tstat or the tstat wire. If it were internal I would think the blower relay or heat contactor/relay were getting stuck AND THE FAN WOULD NOT TURN OFF until you flipped the breaker. Good luck

Handler runs fine but the outside unit, it will kick the fan on for a sec and then shuts off. It does it over and over. sounds like something isn't turning on? what's going on?


Sounds like a bad relay on the fan , if the compressor is trying to start and stopping that kick the fan on and off. That could be due to a low charge if the unit is not cooling properly.

If the unit is cooling properly it is probably a bad relay or contactor on the fan motor.

Other possibility is the fan motor is over heating for one reason or another and if its thermally protected it will automatically shutdown. If thats the case then you need a new motor.

This is a Unico AIR HANDLER in a residential application with heat / cool unit in the attic. With system off (not calling for cool) and fan in auto mode, the blower fan is on high speed only constantly....


Sounds like a sticking relay. You can check the stat simply by remove the faceplate. If fan still runs with tstat cover off its not the stat. Not sure is your blower has a separate relay or if relay is mounted on control board. This can be bypassed with a new relay if you are willing. Good luck!!

Bryant central air unit fan doesn't stop.


This is a condenser fan and as long as the A/c unit is in cool mode, this fan will run. The only time it should shut off is when temperature setting is satified and the unit shuts off.

Fan running constantly in the house


Check t-stat and make sure fan is set to "Auto", that might be why fan is running all the time, or it could be a fan relay that is stuck closed. It sounds like you A/C is over charged or you have a bad high pressure switch, this was a common problem with this manufacture especially in the heat mode.

Inside blower not starting every time


You have a voltage bleed somewhere or a short, whatever you want to call it. Do you have a control board on this unit where the relays are integrated into it or do you have the old type where the relay is separate? Anyway, you need to take a meter and take voltage readings to the motor when it's acting up and when it's running right. I have had the same problem with a Goodman unit before and it turned out to be the tstat! What I would do is remove the cover off the tstat and take a small jumper wire and touch the r terminal to the y terminal. If the motor starts right up, you know it's the tstat. If you have the same problem, then the only thing it can be is a low voltage short to the unit from the tstat, bad control board if you have one, or a bad relay. But if the unit is working fine in heat, it's probably not the relay. I hope this helps.

Fan will come on for heat(auto), but not for AC or set to ON


You have a blower relay in the furnace that's probably bad. In the heat mode the blower is on a temperature relay, in cooling mode the blower has to come on immediately so there is another relay for cooling. The green wire on the thermostat feeds that relay, so if you go to the furnace and shut the power off and find the green wire from the thermostat that feeds that relay and replace it, being careful to mark all the wires before removing them, also the relay terminals have numbers for identification.

Inside blower not starting every time


That's a weird problem. I wonder if the outside compressor is drawing down the voltage in the breaker box enuff to keep the blower from starting up. If you're set to cool but the thermostat is NOT calling for the AC, can you manually turn the blower on fathfully? If so, I would check all wiring connections in the breaker box to make sure they are tight and free from tarnish or corrosion. You may even need to contact your power company and have a higher amperage line installed outside. Do your house lights blink noticably when the compressor kicks on?

While you're resolving this, you could start the blower manually and just leave it on. The compressor cycling on/off shouldn't stop the blower once it's running and it won't draw much current... couple bucks a month maybe.

Hope that helps...
