Product Description

This is an OEM Vermont Castings Fan Sensor (90F/120F) for the FK24, FK26 and FK28 fan kits that work with many Vermont Castings stoves, inserts and fireplaces. This is a genuine replacement part that will ship new in its original packaging, it is not an aftermarket copy.

Vermont Castings Part Number: SRV51704 (Replaces older part number 51704)

Part Description: This fan sensor automatically turns the Blower ON after the fireplace heats up and automatically turns the Blower OFF after the fireplace cools down. This fan sensor is rated at 90f/120F which means the fan will turn on once the fireplace reaching 120F, and it will turn off once it falls below 90F.  A fan sensor is also often referred to as a thermodisc, temperature sensor, and a fan switch – different title but they are all the same part.

Applicable Models: This fan sensor will work with any models that use the FK20, FK24, FK26 and FK28 blowers. Found in many wood and gas Vermont Castings fireplaces, stoves and inserts.
