Dryer quit heating but runs.
Thermal cutoff was open, so I replaced it and the high limit thermostat.
Worked great for a few minutes--then quit heating again. Thermal cutoff is open again.
Have checked the thermal fuse--has continuity, 240 v coming in, heating element has continuity.
Did I get a bad part? Any ideas?
Thanks!

I doubt it.
When you replaced the cut-off did you check anything else in the heater circuit?
If not I would start by checking to see if the element is grounded with a meter.
If the heater element is grounded it can run too hot. This can blow the cutoff right away as even the hi-limit thermostat cannot regulate the temperature. |

I am also going to have to crawl under the house and make sure the vent is not getting clogged. I disconnected the vent hose, replaced the cut off and both thermostats and it is running now ok. Thanks again. dls

How do you check if the heater element is grounded? I have the same problem.

Unplug the unit
Unplug both wires at the heater element.
Measure across the element, should be in the 8 to 12 ohm range.
Then measure from each side of the element to it's case, both should be infinite ohms |
