Hi all, Newbie here.
Was looking at some earlier posts on heater problems to see if my problem has already been answered, since I didn't see my particular scenario I thought I'd make a new thread.
The oil burner started tripping yesterday, when I hit the re-set button, combustion is not slow - I get ignition/combustion immediatly and everything seems fine for a while, heater goes through numerous cycles for a couple of hours or so, then it quits again.
I started hanging around to see what happens, and one of two things has been occuring -
1. It is in idle mode, and when it needs to start, the re-set trips before anything happens, blower dosen't even come on. Or...
2. It starts up as it normally would, igniting immediatly, but after it's been running momentarily ( I've seen it happen at just around 10 seconds, or as long as a half a minute or so) it shuts down prematurely in the cycle, (then a few/several seconds later the re-set button trips and red light goes on).
If I push the re-set button after it does this (after waiting momentarily), it always starts right up, with immediate ignition/combustion, runs again cycling normally for a couple of hours, then shuts down again doing one of the above two scenario's.
I cleaned the nozzel, made sure the electrodes are set to spec. (I have paper work for the heater, was new about 10 years ago), and examined the cad sensor and cleaned the glass (it wasn't that dirty)
What else can go wrong that would make this malfunction on an intermittent nature, and be able to fire up again right away and run seemingly well? Could the transformer be unreliable? Cad cell actually bad rather than dirty? Electrodes bad? Bad spot on the motor? I'd love to hear some ideas on what is most likely the culprit before I try to do anything else. Any and all suggestions greatly appreciated! Dan
