Window AC freeze over blues

If your window unit freezes up the thermistor could be bad. After thaw out and restart simply drop the thermistor into some cold water. The compressor should shut down. If it stays going then the thermistor ain't getting the job done OR the control is bad.

Hot wired window unit

Today I hot wired another window unit. The electronics and fan had failed. The compressor and sealed system worked great. So why toss it? I added a fan motor from another unit with bad compressor and hard wired it to work anywhere cooling is needed. Just plug it in the wall to turn it on, get too cold unplug it! OR A simple low voltage relay with transformer and wall t-stat will control the temp. OR yall could rig most any old cold control to break the power when the desired temp is reached.
Their are 2 kinds of peeps in the world.
Them that has AC and them that don't!
Quote me on that will ya?
Wiring is simple. The power cord has a green "GROUND" wire, a white "COMMON" wire and a black "Hot" wire. The white goes to capacitor, the black goes with compressor run wire and any fan speed (I chose HI speed). The LOW and MED speeds are live and must be taped off separately and away from the frame.
Captain's log supplemental:
Today I added a cold control to the unit. On the unit is a junction block with 2 separate gangs of spade connectors. The gang to the right is empty. The gang to the left has a black HOT wire and a black HI speed fan wire and a RUN wire from the compressor. I simply remove the hot wire and placed it next door in the empty gang. I attached a wired from the cold control also. The other cold control wire I added back to the connector that I removed the power wire from. Now the unit will cycle on and off when the house gets cold.

Direct drive photos




Did a few photos of the tranny removal and spin tube and such. Once you remove the agitator the tranny will slide out after removing 3 bolts. The spin tube will come out IF you remove the inner basket which you should do first when looking for reasons why she won't spin. As you can see this is not a very complicated washer.

Scotsman Ice Machine Revamp


I worked on a Scotsman ice maker over the weekend. I let it run 24 hours starting Thursday night. Friday morning nary an ice cube. This ice maker has an inverted mold. 2 spray nozzle continually supply water to the mold. When the cubes have formed the ice maker shuts down and flushes the res with water while flushing the mold with hot gas. The cubes fall out of the mold and into the bin. Every 20 minutes 6 new ice cubes are made. I had an idea this one was low of gas. Not very much heat coming from the condenser area and the water was cold but not freezing my fingertips. The machine runs on R134A gas. It only holds 5 ounces of freon. It already has some in it. If overcharged the line will be blocked and the compressor will bog down. So how much do you add? I attached a saddle valve and found the system was running in vacuum or in other words negative 10 PSI on the low side. I SLOWLY added a tiny amount of gas never letting the needle get above 10 PSI. When the pressure hung in there around 5 PSI without imediately going back into negative I quit adding and waited. It slowly dropped to 1PSI and stayyed there. In a minute or 2 it shut down and flushed the reservoir, shot hot gas into the mold and loosened up the ice. In the world of dead ice machines hearing the magic ka-thunk of an ice cube hitting an empty bin is a good thing!

Bonus info. Since all auto pilot systems use basically the same prinicible I thought I might add this from RobertShaw. Although products may differ in parts and appearance, they all work the same way. The spark/sensor does 2 jobs. Lights the pilot and then monitors the flame:

Main drive gear worn smooth on direct drive tranny

Here is a rare but nice short and sweet video which shows a worn main drive gear on a Kenmore direct drive washer. This is an easy fix. All you need is some snap ring pliers. The new part comes with a drive gear and pinion. $63 bucks
