So here's the situation. I have a Weil-McLain oil fired boiler with
an older Beckett burner (by older I mean that the boiler is probably
original to the house, 1940 ish, and the burner slightly newer).
Recently I have noticed that the burner will fire for a second or
and then shut off, only to repeat the process a few minutes later.
This happens regardless of thermostat setting. The thing is, it
doesn't always happen. Sometimes the system will work like a champ
Last night I finally got worried enough that the temp in the house
going to continue to drop, so I called a service company. The guy I
got on the phone told me to check the Cad Eye Sensor to make sure it
was clean. Turns out I don't have one...I have an older stack
switch. The service guy that came out today spent about 15 seconds
front of the boiler, pronounced that my stack switch was bad, charged
me $99 bucks and left.
So, does it sound like my stack switch is bad? What does that mean,
(repeated questions to the service tech only got me half-assed
Any and all opinions are welcomed.
