    • Appliantology Live Dojo, Saturday, 4/27/2024 @10 AM ET
      27 April 2024 02:00 PM Until 03:00 PM
      5  
      All Appliantology tech members are invited to join in this workshop on all things Appliantological. 
      We have a special session planned for this one. Instead of the usual Show 'n Tell on a technical topic, we're going to post tech sheets in the comments to this Calendar Event (scroll down to see what's posted so far) and ask specific questions that can only be answered by reading the tech sheet. If you at least try to answer the questions beforehand, you'll get a lot more out of it. The tech sheet and the questions are posted in the comments section below.
      Your mission, if you should choose to accept it, is to check out the questions for each one and try to answer them ahead of time. Then come to the Dojo to see how well you did! 
      Who: This workshop is only available to tech members at Appliantology.
      When: Saturday, April 27 @10:00 AM Eastern Time.
      Where: Online via Zoom
      How:

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.

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.
