I am working on a Whirlpool gas dryer model with a type of problem I am asking for help on from other personnel. This is a fairly new unit probably about 5 years old in very nice condition. I normally use propane to test for heat and it has always been an adequate arrangement. I had to do a cosmetic repair on the cabinet a few days ago and sold it to a customer who took it home and hooked it up to his gas line with no problem. It worked for a short time but he returned it since it will not stay lit for more than about one or two minutes. I checked the gas valve and igniter and it appears to be OK but the gas will not stay lit. If I turn the unit off and restart it it does the same thing---starts to heat but goes out after a short time. I checked the gas valve coils and they are not burnt and the resistance readings are in spec as far as I can tell against a set from another dryer. This is a static test and not when the coils are warm however. Is it possible that the coils are not working when they are warm or should I be looking at another component ? I suspect the coils but is there a reliable way to test these either during the heating cycle or off the unit or should I just replace them and see what happens ? HELP and advice would be appreciated.
