Product Description: 12VDCTDR

ONLINE DROPSHIP PRICE ONLY

The replacement Time delay relay is for use in older furnaces that use a standard 12VDC ignitor board. The TDR has a 4 second delay before applying power to the fan motor, and a 2 minute cool down period at the end of the heat cycle before removing power from the fan motor.
