Rebuilt gasvalve

[Reg]

I was wondering if you can have a gas valve rebuilt. I have a ADC Dryer that uses a glow bar to light up the fire but the electric gas valve that lets the gas open and flow to light up the fire is not working. They are about $350 but I was wondering if it can be rebuilt somewhere.

Thanks Reg

I don't know of anyplace that repairs gas valves for the Laundromat business. However, there are two ways to go that may be productive.

1. Try your local heating and a/c store. They work on thesse things all the time and can probably repair it.

2. Open it up yourself and clean the diaphrams. Usually, a speck of dirt on a diaphram will be enough to clog up the works (make sure your solenoids are working first...another common problem).

You usally only replace the coils and should solve the problem. What model ADC are these and how old are they? Give me some more info and I might save you some money. Can you use a volt ohm meter?

they are 25 BH around 1986 models has 3 coils on the vlave. I have a good friend next door that can use the ome meter ( I know I need to learn and I will ). I also have another valve left there by the last owner but I don't know if it is any good , looks like new but it is used.

I have eleven old SQ 30lb dryers that kept leaking past coil even with new coil installed. I finally gave up and installed all new valves. It's just not worth the aggrevation.

Reg, since you have another valve get it out and compare the ohms of each coil to one on the machine and the one old one. They should be very near the same.If one reads near 0 ohms or maybe a couple thousand ohms higher than the other that maybe the problem. I'm not familar with the older ADCs with glow bars. But you can take each coil one at a time from a working dryer and try it and you can ellimate the coils that way. With a glow bar system you still need a sensor that detects the heat from the glow bar it should be right beside of it, change it with one one a working dryer if that dryer doesn't work you found the problem. I would never try to rebuild the guts to a gas valve but most of the time the problem is a coil or another device. remember that you can always swap parts or read (ohm meter) parts from a known working machine and compare the readings.


Good luck and don't spring for the new gas valve unless there is no other choice.
