about Boiler Hi Limit Switch.

Can I clear Boiler Hi Limit Switch myself?

On the boiler, behind service panels. Its reset is meant for a technician after the cause is found.
Why did my Blodgett boiler high limit trip after a water outage?
A boiler heating without water overheats fast. Restore water and have the limit reset and the heaters checked.
Is Boiler Hi Limit Switch the same as Boiler High Temp Error on a Blodgett?
