I have a 2 yr old Kenmore dryer that won't heat. I've tried disconnecting the sensor (part # 5303281135) and bypassing it and the ignitor still won't light. Could it be the Saftey Thermostat mounted on top of the drum (part # 5308015399)? It was working fine and then 2 days ago in the middle of drying a load, the heat just quit. The drum turns fine and it circulates air, just no heat.

Thanks John

I realize having a meter would be the ideal situation but I don't have one. I guess what I'm asking is, is there any other logical or common part failure that causes the ignitor not to light other than these two parts?

Well, since you've bypassed the flame sensor already and it didn't help, the sensor is probably ok...

Post the complete model number. Should be something like 417.xxxxxxxxxx

Of course it's much easier if you had a meter and were familiar with using one - you could check the flame sensor for continuity (open = bad, closed = good), you could also see if the igniter is getting power (if igniter gets 110 volts and won't ignite = broken igniter), etc. But hey, we can't expect everyone to own a meter :). The downside of not having a meter is we may end up making a wrong guess and have you replace a part you didn't have to replace.

Common reasons for igniter not functioning: Bad igniter or no power to igniter. Second could be caused by a bad thermal fuse, bad flame sensor, or bad timer (very rare). Post the complete model number and I'll take a look.

Really? Can you describe exactly what happened?
