Dayton G73 Inop

[ted13b]

I have a Dayton G73, it's a couple of years old and now it won't heat. No blower, nothing. I've checked, and I have 240 to the unit. Do they have a built in breaker? I don't see one on the internal circuit diagram. Any ideas?

Any troubleshooting ideas? Is there a way to check the thermal sensors, and will the fan blade if one of them fails?

I'd first check connections and power. Next I'd check the thermostat (careful, disconnect power before doing tests!) and the heating element. Just a WAG (ok, based on experience) but I suspect your thermostat is farked.

I checked and I'm reading 232v at the unit. If the tstat is gone, will the blower work? And how do I check the tstat? Jump it out or check resistance?

1. Mine the fan turns on with the element.
2. Ohm meter, with power disconnected.
3. You could jump it (power disconnected) and then reconnect power.

I ohmed out the tsat and it reads open...bad tstat?

Sounds like it is bad.
