what does a thermal cut off do

A  Answered on 8/21/2016 by InyoPools Product Specialist Stacey M.

Hello Rusty, The operating principle of the thermal cutoff is a electrically nonconductive pellet that under normal operating temperatures will hold the spring loaded contacts closed. When a predetermined temperature is reached, the pellet melts, allowing the compression spring to relax. The trip then slides the contact away from the lead and the circuit is opened.

How can I tell if this has tripped or gone bad?

A  Answered on 7/5/2018 by InyoPools Product Specialist Lennox H.

HI, Dave. The Heater will give you an error code or you can test for continuity (open circuit).
