Evaporative cooler/electrical problems


We have an evaporative cooler on the roof of house. It was working fine until one evening it was still pretty hot, so I turned it on. We have a dial switch where you pass through the pump setting first and the pump did come on. However, no blower. I smelled plastic and turned it off fast. DH felt maybe the motor needed to be replaced (this one was a year old) so we bought a new motor. Well after it was installed, we still only have pump but no motor. So now we buy a new switch and an electric tool kit with multimeter. Well not sure what to do with kit. Checked some batteries, which was a plus, but not sure what good it will do for checking the cooler. So now with new switch and new motor, no cooler. And I am burning up. We have now spent $180 and it doesn't work, and since I have become disabled (working on disability, but nothing yet) we are down to 1 income, and high frustration.

Is there anything we have overlooked? I don't know where to turn and the funds for an electrician are not there with the above purchases. Any advise or direction would be appreciated.

Thanks! Trixie

Evaporative cooler/electrical problems


if the fan motor is good check the capaciter ,listen to the unit the compressor will come on and when the unit reaches temp the relay will click then u will hear the fan try to come on, try to push the fan blade with a stick ,if it runs the cap may be toast .my first house i lived with a furnace motor like that for 2 years ,also try a continuity ? check ,to see if the windings are burnt.on the motor .a capacitor only costs a few $if u need to replace the motor ,replace the cap too....
