The original Honeywell fan control/overheat limit thermostat is no longer available for the VR range of warm air heaters. A replacement fan control/limit thermostat kit (part No.33-67-986) (https://www.reznor.co.uk/product/honeywell-fan-limit-stat-retro-fit-kit/) is available for VRA models 12-145 and VRE models 12-60.
What is the part number for the limit switch on the Benson VR-2 Heaters?
