no heat, whirlpool electric cryer

Dryer Repair

I have a whirlpool electric dryer that does not heat. Model# LE7680XSW1. I have continuity in thermal fuse, the cutoff thermostats (both bottom & top) and the other thermostat below the thermal fuse. The "ring" cycle thermostat (whirlpool part # 61894) (25 on the bulkhead parts diagram) attached to the thermostat below the thermal fuse does not have continuity. I tried jumpering this and still did not get heat. I checked for continuity in the heating coil, and have it, both at the terminals and across the coils after the ceramic insulators. Oddly enough, when the dryer runs, I get voltage through the coils but no heat. (Am I tripping? - how does that work?) The voltage from the front wire on the coil (front is front) is about 28v and the voltage on the other wire is 110v.

I’m not sure how old the dryer is. When I opened it up, the whip was bad. I replaced it, and checked power. left to right - 110v - common - 110v. 220 across L1 & L2.

Am I checking the cycling thermostat correctly? Can I get voltage (and continuity) across the heater coil without heat?

Should I look at something else?

If the thermostat heater has no continuity, then would that stop the heater from working?
No, the heater should still cycle.
If it was blown you just would not have the lower heat settings, it would always run on high heat.

Is there a case where the cut-offs and hi-limits would show continuity, but not work?[/COLOR]
Not that I know of.

Do you have any idea what it is? it is #26 on the bulkhead diagram and the only info is "not available."[/COLOR]
I am not sure what it is but it looks to me that it is a filter bypass. perhaps if your lint filter gets too dirty it bypasses it so the unit does not overheat.
