 Honeywell L8148E Aquastat High Limit Control
Author: Jbii24 (NY)

My new aquastat does not shut the boiler off when the temperature hits the high limit. A temporary workaround I am using is a wedge under the dial which slightly raises the dial, and now it works perfectly. I obviously do not want to rely on a wedge in there, so I am wondering if anyone knows how to adjust the dial permanently to fix the issue. Thanks!

is the bulb pushed all the way into the thermometer well and did you put a dab of heat transfer grease on it?
