Our evaporative cooler fan does not start when we turn on our unit - it will run if I get up on the roof and start the fan blades spinning... We could smell a burnt motor smell when the problem started. Is it just a fuse? or is it a new fan motor?

I was expecting to find this relay. It's not there. My unit has a rather complicated looking circuit board. The circuit board seems to have been made by Emerson Climate Technology. On the top edge of the circuit board is printed "Climate Talk" and the number "4672H". There is also a Bar Code sticker affixed to the circuit board that bears the number 11014630400034. Where do I connect the thermostat wires (red & white)?

My heat pump will not come on in HEAT or A/C. I thought I might have a simple defrost control board problem, but still no go after replacing the board and the defrost relay. I checked the pressure switch and it is not tripped. I've checked all the circuit breakers and they, too, are all set. I've checked the outside unit using the "test" switch inside on the start relay and the unit will come on, but won't stay running on it's own. When I select HEAT, I wait the necessary five minutes for the un

Furnace shuts down before heat temp meets thermostat. Furnace unit starts frequently. Service installed new limit switch and a new circuit board but furnace unit continues to malfunction. Same problems after service as before limit switch and new circuit problem installed.


Has any one checked your thermostat. as soon as the furnace shuts down then turn up the stat and see if it starts right up. i would think the stat function should have been checked also. ... Air Conditioners

I have an Amcoraire model AOS091HX that also displays an F1 error code. Fuses were blown on the outside unit. I read about the fix by replacing the capacitors in the middle of the circuit board. I contacted Pridium and was told the circuit boards from China have been on order for six months, so I have nothing to lose by replacing a capacitor or two. Any other advise would be greatly appreciated.

Dometic said one of the relays was welded or burnt out or closed which is causing the problem. unit works just doesnt stop humming when turned off .Not likely two bad control boards?? Mod.9597.....
