Whirlpool dryer model WGD5900SW0 heats sometimes

4 posts in this topic

Mostly it doesn't heat.

I've checked the thermistor and thermostat behind the back panel, and of course there's continuity (because sometimes it does heat).

The igniter always glows for a minute, even when it fails to flame-on.

When it fails to light, the normal "click" is accompanied by a rattling type of noise, sounds like a solenoid not pulling in to me.

It seems to follow the "Roger Rabbit rule" for lighting -- only when it's funny. Such as when I have it all pulled apart to try and diagnose it.

Sounds like I should invest in a new set of coils, at the minimum. My question is whether I should go for the whole gas valve assembly -- is it probable that the failure is at least partly a mechanical one (wear, friction, rust, whatever) in the valve rather than solely a coil weakness. Is there an inspection or diagnostic that would answer that (short of buying only coils, then eating their cost when it turns out I needed the whole assembly).

Secondary question: since the dryer is 10 years old, should I replace the igniter while I'm at it, just because they do age. What is the expected lifetime of an igniter?

Yep, sounds like anudda case of bad gas valve coils. Very common repair. Easy and inexpensive, too.

Thank you sensei and Host!

Since experience tells you that trouble with the mechanical parts of the valve assembly is unlikely, I will proceed with coils only.
