Overview for White Rodgers 21M51U-843

The 50M51-843 is a universal replacement control for two-stage automatic gas ignition controls employing a microprocessor to continually monitor, analyze, and control the proper operation of the gas burner and inducer. The 50M51-843 controls a multiple tapped induction circulation blower. Signals interpreted during continual surveillance of the twostage thermostat and flame sensing element initiate automatic ignition of the burner, sensing of the flame, and system shutoff during normal operation.

The 50M51-843 quickly and easily replaces White-Rodgers 50M51-XXX controls. This kit includes: a 50M51-843 Ignition Control Module, a 21D64-2 Ignitor Kit.
