I've got a 4 year old Brock oil furnace that hasn't given us any problems for 3 winters now. I've occasionally (about 3 times) had to press the red reset button over the last 3 years, but I've now got a problem.
I have to reset the furnace constantly to get it to run. It'll run about 5-10 minutes then shut off. The only other time I had this problem was when I tried to hook up a digital thermostat.
I've got an isolation relay, if that'll help, but I'd like some advice on what could be wrong.
