Honeywell oil boilers are hot water heaters for the home that are controlled by a central thermostat. The company warns in its technical manual that the oil burner does not have any parts that are serviceable by homeowners, but if issues arise with the boiler, some basic troubleshooting efforts can often identify the problem source. This may allow the user to solve the problem without having to contact Honeywell.
Turn the main switch on the Honeywell oil boiler to “On” if the boiler is not running. Check the oil tank gauge to see if the tank needs to be refilled with oil.
Open the air release valve on the radiator slowly if the boiler is also used for heat, to release excess pressure if there is a rolling sound in the pipes when the boiler is operating.
Press the red reset button on the main boiler control panel if the Honeywell boiler shuts off unexpectedly. Check the area around the boiler to ensure there is nothing blocking air flow to the vents.
Tips & Warnings
- Contact Honeywell if troubleshooting efforts do not solve the problem. The burner nozzle might be clogged, the filter might need to be replaced, the heating system might need to be bled or the boiler has locked out as a safety precaution. These are all factors that should only be serviced by a professional.
- Never touch the boiler when in operation; the surfaces may be very hot.
- Keep children and pets away from the boiler.
