GE Air-Conditioner Repaired
I repaired the circuit breaker plug on this A/C window unit around 1 ½ years ago. I didn’t write an article about it because I was new at learning electronics and did not have my camera or my digital microscope camera. It quit working again – so let’s open it up and see what is wrong with it.
You can see in the photos how the hi-voltage lead has broken from the PCB and the LED anode lead. I checked the LED and it was still good.
So I soldered a piece of a lead that I clipped off of a 3 watt resistor to give the connection more strength and to also make sure power reached the resistor on the opposite side of the PCB in case the track was broken. It seems to be pretty sturdy now.
Although my nephew says nobody took it apart, I know that someone did because they lost the spring that goes around the nub and inside the cup of the slide lock that locks the hi-voltage contacts together so the unit can get power. As you can see in the photos, I need a spring with an ID of at least 1.7mm and about 7mm long. I don’t have one that size so I’ll just make one as a temporary fix. I have some small stainless steel wire, but it isn’t spring steel. I’ll find a good spring later and install it. I went ahead and soldered the homemade spring into the cup of the slide lock to make sure it didn’t pop out and short on anything.
Here are some pictures:
I carefully wrapped the wire around my precision screwdriver that has an OD measuring about 2mm. Then I heated the spring red hot and quenched it in cold water several times. It should last a few days until I can find a spring with stronger steel.
Success, it’s fixed for now until I can get a more dependable spring. I hope you guys enjoy the article.
