Central Boiler / temperature controller

« on: March 08, 2014, 06:24:19 AM »

i've had a 4036 for about 9 years, mostly trouble free...last night i noticed that the house temp was down, and that the digital temperature display on the furnace was out...went out to look more closely, and noticed that, altho the damper was closed, the lights on the furnace still worked...by the time i got back in the house, the temp display was back on and the damper was now open (water temp was down to 166- it's set at 195)...it worked until this morning, when the same thing happened - temp display was out and the damper was closed...naturally i was confused...

thinking loose wire or bad connection...am going to start looking this morning as soon as the sun gets over the mountain and warms things up a bit more...i've got an oil furnace and a wood stove so the house isn't cold but i'd like to fix this...dealer won't be available til Monday...

anyone have any ideas?
