My grandmother has a Maytag gas dryer that's about 30 years old and it's having trouble heating. The ignitor will come on and the flame sensor turns the ignitor off like it should then the gas comes on and it lites. After 10 to 20 seconds the burner goes out and it won't relight. I replaced the gas valve coils but no help. I want to fix this dryer if possible because 1) it's better than anything you can buy new and 2) my grandmother is 81 years old and I don't want her to have to buy a new dryer when there's no telling how long she'll need it. Little morbid but truth is truth. Any suggestion? The lint trap is clean and I'm almost sure the vent is open and working like it should ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |

| Try cleaning the flame sensor or replace it. The igniter is on a timer not flame sense. The controller doesn't see flame so turns off gas. |

I'll check that next. That was my original thought because that's how the furnaces that used to be used in chicken houses work but I found somewhere on the internet it said different. That's what I get for listening to the internet. ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |

yeah 30 year old tech is good stuff... new stuff, not so good.... I 2nd the 'flame sensor'. Probably 'old school' and 30 years worth of soot finally 'hid' theh flame from the sensor. hope you have good luck ! ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

| May not a apply,but if propane it could be the regulater going bad. When not using heater just the water heater had this. The copper pigtail was flacking off and plugging regulater. Replace the copper pigtail from tank and all was well again. |

The only reason I'm not thinking regulator is the heat and the water heater both work fine. If a flame sensor can't fix it then I'll look further into the gas lines ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |

| I think if the thermal coupler is bad, it wouldn't light at all. |

A bad thermal couple will let it light but not stay light. Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

Who'd a thunk it?? The vent pipe came off. Put it back on, dried a load of clothes like it always has. ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |

Bet that soup is the best around. Mom had "the touch" and even using the same recipe my wife or I neither one can even come close. With this cool weather just around the corner I hope she made you enough to last a day or two. Glad you got the dryer fixed, don't you love it when it is something simple and takes you forever to find it. ------------- Just an old country boy saved by the grace of God. |

Hehe. Yeah I hate it when it takes forever but when it happens that way all the time you get used to it ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |

If the gas dryer is 30 years old, it doesn't suffer from an excess of 'safety brains'... all the protection is basically inside the gas valve... which is essentially the same valving that's used in a furnace, or a hot water heater. Most likely, the reason the flame went out with the exhaust vent removed, was a rapid decline in the amount of available oxygen... the flame was suffocated... by exhaust... which means you're lucky... could'a been tragic. If it uses a hot-surface ignitor, the ignitor current flows through a detection solenoid in the valve... if there's insufficient current through that HSI, the gas valve will drop out after about ten seconds. It has a thermocouple flame sensor of some sort... typically, they're same scenario as an HSI... presence of flame provides a MILLIVOLT, low current signal strong enough to hold in a tiny solenoid in the valve. no flame, no hold magnet, it will NOT flow fuel without it. Note that valves will LIGHT without those sensors being satisfied... because there's a 'start circuit' in the valve that can be triggered for a few seconds in order to get ignition, but after a few, that circuit will release, and the flame will go out, unless the safeties have determined that a flame has been attained. ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem.
