in Gas Heating
my Mascot was working fine this morning, took 2 showers and no issues. After second shower the unit was calling for hot water even those no appliances or faucets were on. Which cause the unit to throw and error code 79 and locked out. This is a " High Limit Reached" as probable cause. Does anyone have any insight on if this is something simple or i could be in some trouble?
Thanks

Hello @raider1,

I would also suspect a failing sensor.
