Arrived on site to diagnose reason for no heat on propane boiler. After our initial inspection, we provided an estimate to dig a bit deeper for the diagnosis as it was not obvious. We first checked power to the control board from thermostat. It was good so we went down the line of controls until we found that the flue gas blower motor was receiving proper voltage but would not operate. We checked the amperage and found it was over 1amp which is more than the fan is rated for. Reached out to the supply house to order the part. It should be at the shop sometime late next week. We will be in touch to schedule a return visit when it comes in. Thank you for your patience!
