These standard interface boards are also used in a number of fryer types besides the H50 Series. The

information contained in this section applies to H50 Series applications ONLY.

Earlier design 806-3398 boards (used from June 1996 through July 1999) contain two heat relays (K1 and K2) that switch 24VAC to the ignition and gas valve circuits when the computer/controller heat logic circuit calls for heat. Relay K4 switches 120VAC to the blower motor when either K1 or K2 closes. The relays on these boards are soldered on – if one fails, the whole board must be replaced.

The later design 806-3398 (and 106-0386 boards that replaced them in current production fryers) have only two relays. In this design, K2 and K3 are double-pole-double throw (dpdt) relays that supply 24VAC to the ignition and gas valve circuits, as well as 120VAC to the blower motor. The relays on this board plug into sockets. If a relay fails, that relay can be replaced.

The tables below identify the diagnostic LEDs and their meaning.
