When I arrived on job site, customer was unsure how long the boiler had been out so after checking the system I found that the damper motor was bad so I bypassed it but it still wouldn’t work so I had to bypass it with wires after doing that, the boiler came on a ran for a few minutes, then shut back off. I’ve then found that the high limit switch terminals were corroded and not allowing voltage to pass off Through them, I made the best connections possible with the condition of the switch and then boiler fired off. Boiler was running when I left, we will need to follow up with a price on a new draft motor and rollout switch. Please mail the invoice.
