What it is
The 173760 is a relay printed circuit board supplied by Ideal for its commercial and IStor appliance ranges. It is the control centre of the appliance, monitoring and governing every process that runs through the switches, sensors and thermostats. The board also enforces the appliance's safety procedures, shutting the boiler down when a monitored condition falls outside its limits.
Signs this part needs replacing
- The appliance fails to fire or does not respond when there is a call for heat.
- The display is blank, scrambled or shows repeated fault codes.
- The boiler locks out intermittently, often after the board has warmed up.
- Relays can be heard clicking but the fan, pump or ignition sequence does not follow.
- Safety lockouts occur with no obvious fault at the sensors or thermostats.
Before you order
- Confirm the GC number on the appliance data badge against the compatibility list before ordering, as the board is used across more than one Ideal model.
- Check the existing board for the printed part number and compare it with 173760 and the alternative number 1179607.
- Isolate the electrical supply and photograph the plug and loom positions before removing the old board.
