12VDC TDR 12VDC Time delay relay 4 sec

The Dinosaur Electronics TDR Time Delay Relay is for use in older furnaces that use a standard 12 VDC ignitor board. It has a 4 second delya 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. It fits in the same location as the original.
