【Replacement Number】Replaces UIB S, UIBS Post, UIB L and UIB L Post Dinosaur ignitor circuit boards; Replaces 520741 520814 module board.
【Application】The 12VDC ignitor board is used ①for Dometic, Norcold and Servel refrigerators; ②for Coleman, DuoTherm, Hydro-Flame and Suburban furnaces; ③for Atwood, Morflo and Suburban water heaters. *Note: Works in any 12 VDC furnace/refrigerator/water heater that uses a standard ignitor board.
【Security Setting】The fuse on the electronic ignitor circuit board can protect the board from short circuit damage to extend its service life and work better and safer on your device.
【Flame Monitoring】When 12V DC power is supplied to the circuit board, there is a 20 second delay before ignition allowing the furnace to purge any unburned gas in the combustion chamber before ignition occurs. After the delay, the board supplies a high-voltage spark to the igniter and supplies 12V DC to open the gas valve. The board will then monitor and confirm the presence of a flame.
【Warm Note】When installing the UIB S board in a water heater or refrigerator, please use a transparent plastic cover.
