Ruud heat pump makes a clicking sound

Ruud heat pump clicks when producing heat when the compressor comes on. No click is heard when only the fan is running.

The term H.P. is just a reverse flow a/c. do you have one big machine outside or do you have the h.p. outside with the "airhandler" inside. up in the attic, a closet,garage, etc?

if the sound you hear is coming from the airhandler, then it is the heat strip relay/contactor kicking i and out providing supplimental heat.

if it is the outdoor machine, or h.p. then it can get tricky.a onetime click is probly the contactor sucking in or the reversing va;ve energizing.if it is numerous clicks then it becomes a low voltage control problem.

a loose connection can cause this.check around the contactor, reverse valve solinoid, and control wire nuts.Quite possibly a bad relay.look for the rvr solinoid not being on the 4 way valve properly.

good luck with low volt problems.

Many thermostats have a setting to keep the fan running instead of cycling with the compressor. Check its settings.

New to wood furnace. Does the blower kick on automatically


Not sure what brand or model you have, but usually the fan wont come on until it heats up enough to close the fan switch which powers the blower

I have a Rheem Classic Super Quiet 80 gas furnace (for heat). The fan stops when the "heat" turns on.


Any time I ever had trouble,first thing to suspect is the thermostat.
They lose contact sometimes and sometimes you tap the face and they work til next glitch.
If the thermostat has some years on it,go ahead and replace it.
Can't you just leave the heat and fan in auto? That would be best,I think. don-ohio

My display was blank except for change batteries. I changed them and the display is flashing (heat on). The heat clicks like it's gonna come on but nothing happens


You have lost voltage to the tstat. Sounds like it doesnt need batteries to begin with. Check your breakers first, if not tripped you have internal problem

I have a older Carrier heat pump, model 38YKC060. Does anyone know how cold it will continue to work at?


Heat pumps are of little or no value at temps around 40 degrees or below. And if you use the strips it will cost a small fortune if you have relatively high electric rates as most folks do.

We have royal red furnace to heat our home.The fan dose not stop.


Details.......does the furnace function normally otherwise? Might just be a stuck fan switch. Make sure the thermostat hasn't been set on Fan ON setting or summer air circ. on older furnaces.
Find the fan switch and tap it and see if fan quits. If it does,fan switch is bad.probably. Always make sure your air circ. filter(return air to furnace) is replaced every 3 mo. or so,too. don-ohio (:^)
