Question about Mastercool 67680 Evaporative Cooler Air Conditioner

1 Answer

Auto does not work right.

When our Mastercool is set to Auto the fan cage motor will switch to on,off,on,off,on,off. I push the Auto button off and just run the fan.
Is there something I could check or replace myself?

Mastercool plus 6500 thermostat problem


Posted also on the Cooler quick cycling problem:
My Master Stat Controller (CC2000A Rev 2003) was in 2 parts. The Thermostat unit in the house and the Power Control unit in the Cooler. The power Control unit was mounted on the squirrel cage fan housing so it vibrated some when running. That means the components vibrated slightly with respect to the PC board. Especially the larger components. My first symptom - Intermittent failure to turn the water pump on. I could see a faint crack in the solder around the pin of a relay on the PC board. Re soldering the PC pins solved that problem. Later, the second symptom was quicker than usual on-off cycling of the fan. I re-soldered all the pins on the PC board and all problems subsided. A better mounting place for the Power Control Unit would be good, but outside of the cooler might be a thermal problem here in the hot desert south west.

Squirrel cage installation.


If there is strong air flow blowing into the house the sq. cage should be OK. Possibly you need to replace the pads and make sure that the pump is not clogged and is distributing enough water to keep the pads wet.
