Gas dryer flame is orange and blue
Model Number: MDG4057BWW Brand: Maytag Age: More than 10 years
It wasn't getting warm.
Replaced the "Dryer Gas Valve Coil Kit" and the "High Limit Thermostat"
Cleaned the "Burner Tube Assembly"
No exhaust blockage (ran with door open)
No apparent intake blockage (gets hot when there's a flame)
The symptoms remain: The "Flat Style Dryer Igniter" glows, the gas comes on ignites, and in less than a minute the "High Limit Thermostat" clicks off and the flame stops. If I continue to let it run (without flame), the "High Limit Thermostat" reconnects and in a short bit of time the cycle repeats.
I shorted the "High Limit Thermostat" and the flame would continue, but, of course, it would get too hot.
I noticed two things about the flame. It seemed a little wild, lapping "High Limit Thermostat". Also, the flame was about 1/2 orange, which indicates incomplete combustion. The latter is not good as that is a source of carbon monoxide.
Could it be that there is too much gas? In trying to figure out how to reduce the gas flow, I found a screw on top of the "Dryer Gas Valve", which I loosened and it came real loose. I didn't want to mess with that so I re-tightened it. Is that just a cap to the pressure adjustment? If so, can I back off the gas? If there is an adjustment screw under the suspected cap screw, do I turn it clockwise or counter-clockwise to diminish the gas flow?
Is this dryer repairable?
