things i have tried.
1. the breaker checked good.
2. heather elec. switch check good.
3. i got 118 volts from side to side on the switch assembly. no volts up and and down on switch assembly.
4. 114 volts across heating element.
5. i was told if the heater works on gas the DC switch is working ok and if you have voltage measureing from switch to switch the AC switch is ok.
6. did an ohm check on the element w/o pulling the element and it checked ok.
7. after all these items checked ok i was told that you could have a calcium build-up on the heating element which would cause the element not to heat up. after pulling the element to inspect for calisum i replaced it. there was very little calcium on the heating element.
8. i havn't pulled the on off switch to look for loose wires.
by the way this problem started while i was parked at the monty plant.???
thanks
