How To Troubleshoot A Beckett Oil Burner | Wet Head

I have a texaco burner head that works properly when firing. After the oil burner shuts down ( after we hit the room thermostat set limit) the burner head drips oil from under the pump.

Boiler ignores thermostat calls after zone valve

2020-11-21 · But the boiler continues to ignore the thermostat calls. There is an external transformer on the boiler. My boiler is a burnham es2. Ideally I'd like to get all three zones wired up so they can call the boiler for heat independently, but right now I'd settle for just one zone to be wired properly and be able to call the boiler from the thermostat.

Common Furnace Thermostat Problems - The Spruce

The transformer is typically located inside the service panel on the furnace. You can identify it by the small-gauge wires (similar to telephone or doorbell wires) that run from the transformer to the thermostat. Make sure to shut off power to the transformer's circuit before testing or replacing it.

Boiler turns off before thermostat reached, but starts

I have a 7 year old Lennox steam boiler that has a new problem. When turned on, it runs for about 20-30 minutes then shuts down, regardless of whether it has reached the thermostat temperature. If I switch the boiler off using the switch on the boiler, then turn it back on again, the boiler starts up and gives me another 20-30 minutes.

There is NOT 24 volts available at the thermostat.

The thermostat leg is only one (the hot) leg of the 24 volt circuit. So no you wouldn't read 24 volts across R & W. You may have another issue since a T87 should work with just R & W connected. You might try jumping the 2 leads at the thermostat and if that gives you intermittent operation then jump TT (R&W on a furnace)at the boiler/furnace.
