50A55-843 Ignition Control Module, Universal Integrated Furnace Control Board Furnace

The 50A55-843 is an automatic gas interrupted ignition control that employs a microprocessor to continually monitor, analyze, and control the proper operation of the gas burner, inducer, and fan. Signals interpreted during continual surveillance of the thermo-stat and flame sensing element initiate automatic ignition of the burner, sensing of the flame, and system shut-off during normal operation.

• Input Voltage: 25 VAC 50/60 Hz. Max. Input Current @ 25 VAC: 0.45 amp. Relay Load Ratings: Valve Relay:1.5 amp @ 25 VAC 50/60 Hz 0.6 pf .Ignitor Relay:6.0 amp @ 120 VAC 50/60 Hz (resistive). Inducer Relay:2.2 FLA–3.5 LRA @ 120 VAC. Circulator Relay:14.5 FLA–25.0 LRA @ 120 VAC.
• The 50A55 has only one serviceable part–an automotive type fuse, which protects the low voltage trans-former from damage if its output is short-circuited. If the fuse has opened up, remove whatever caused the short circuit and replace the fuse with only a 3 Amp automotive type fuse. If the fuse is not the cause of the control's problem, replace the entire 50A55 control. There are no other user serviceable parts.
• Superior Quality, advanced microprocessor-based high-precision PCB manufacturing, soldering and assembly technology, professional tests to ensure optimal performance and long-lasting reliability.
• Note: to save yourself some hassle, please take a picture of the old one before removing it.Make sure getting the wires on the correct terminals. Please feel free to contact us if you have any questions about our products, your satisfaction would be our greatest motivation.
