Honeywell L7224 - Err 1 comes back after new sensor

in Oil Heating
Hello All,
I woke up to a bit of a chilly house this morning. Inspection of the furnace yielded an err code "1" on the aquastat screen. I replaced the sensor and the furnace will start run for 5 sec and then the error comes back. can unplug the sensor and then plug it back in and 5 sec run again.
Just curious if I need to replace the entire unit.

Maybe it's the plug in the aquastat itself. I assume the sensor is all the way in the well, making good contact.

yeah you are correct all the way in and tight fitting. no corrosion in the well0

I've never had to replace the sensor on that aquastat. But since you replaced it and it's still showing E1, I'd assume the aquastat is bad.
On a last ditch effort, I would remove and check/clean the outer well surface.0 -
its a head scratcher... left the power off for 2 hrs while i was figuring stuff out and checking stuff. Turned it back on and went through the settings... and it started working... ordering a spare aquastat to have on hand now.. just in case0
