Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.

1) Have you confirmed at the LINE side voltage of the heater connection (house wires) that you have 240 volts across the 2 hot house wires?

Customer: replied 9 months ago.
119 volts each leg
Expert:  Kevin replied 9 months ago.

OK, Thanks for the confirmation.

1) Each leg to ground having 119 volts is correct.

2) What about phase-to-phase voltage? Can you measure 240 volts across the 2 hot conductors?

Customer: replied 9 months ago.
did not check that
Expert:  Kevin replied 9 months ago.

1) Confirm if you have 240 volts from phase to phase. If so, then the breaker and the circuit are obviously OK.

2) If the proper voltages exist at the LINE side then the only 2 other possibilities are either a faulty T-Stat or a defective heating element or a faulty wire splice/loose termination.

3) A continuity tester or an Ohm meter can confirm if an open heating element or a defective T-Stat.

Customer: replied 9 months ago.
will try those tests
Customer: replied 9 months ago.
Must leave now for an appointment.
Expert:  Kevin replied 9 months ago.

Very good.

1) When checking for continuity and/or resistance, make sure the circuit breaker is in the OFF position and confirm that no voltage is present at the LINE side connections.

No problem, just reply back to me when you have an opportunity and we can take it from there.

Let me know what you find...........Thanks...........Kevin:)

kevin test for phase to phase turned out bad braker.
Expert:  Kevin replied 9 months ago.

Thanks for confirming.

Yes, that is why I requested that you always measure phase-to-phase on a 240V circuit.
