Flight Systems 56-4323-00 Onan 300-4323 Generator Coolant Temperature Alarm Board

Flight Systems part number 56-4323-00 Coolant Temperature Alarm board replaces Onan part number 300-4323, and is used on Onan model 20 DKAE, 25 DKAF and 10 DKAH generator sets. The board is installed directly behind the coolant temperature gauge on the control panel and monitors your coolant temperature. Relays on the board provide signals to the engine control board (300-4296) for low coolant temperature and high coolant temperature pre-alarm. The Flight Systems 56-4323-00 replacement incorporates additional protection against voltage surges. That protection extends the life of your board, and is not found on the original Onan part. Our replacement is manufactured in the USA and comes with a two-year warranty.
