Window a/c thermostat switch

4 posts in this topic

My ancient Montgomery Ward 220v window unit quit working. With the thermostat switch (rotary knob--rheostat?) bypassed it seems to work ok. Can I just leave it this way, as it's always on full cold anyway?

Thanks.

Yes but it will never cycle off; unless you turn off breaker etc

Yall can bypass all the controls however once the ac has cooled down the house then it will freeze over. I hot-wired one and made this video:

There are 2 different knobs: One turns the unit on--a/c high, a/c med, fan hi, fan med, etc., and the other is the thermostat. It can be turned completely off, or turned to a progressively colder setting--the rheostat function I mentioned.

My concern was icing, but I've no way of knowing if the unit has ever gotten the room/house cold enough for the thermostat to cycle it off.

I watched the video but couldn't tell what I was supposed to be seeing?

Thanks.
