This heater - Hayward H series - H1001D1 / ABG 1001 - has worked well until a few days ago. It will ignite and run for about 1-2 minutes and shuts down.
After 5-10 minutes I can start it again but will also shut off again.
I took the thermostat unit apart because it no longer felt like there was any resistance when turning it. The tube from the temperature bulb attaches to a circular piece of metal inside the switch. There appears to be markings on that circular metal piece from coiled wire - which is no longer there.
I think this type of thermostat is a reostat. It is not micro switch.
Does this sound correct for this model heaters thermostat?
If so, then if that internal wire has worn away then of course the thermostat would not work and the unit would shut down
Does this sound correct because I don't what else to check.
How do I check the high limit switches?
Thanks for the help
