The element and wiring loom check out OK. The resistance across the NTC is 33? and again loom is OK. The heat and temp selector switches are the same so I swapped the over to eliminate the selector. Is no heat a known problem for the modules on this machine? Thanks.

A common failing, on any make, why the relay on the module should fail I would say.

I will check the NTC again.
