EOGB MMI810 Mod 13 Control Box

The MMI810 Mod 13 Control box is an EOGB burner control box used on Honeywell and Satronic control platforms. It manages the burner sequence on the appliance it is fitted to, handling start-up, flame supervision and lockout. The unit is supplied under EOGB part reference S01-MMI810-13.

• The burner runs through pre-purge but fails to reach ignition and locks out.
• Repeated lockouts on start-up that clear only after a manual reset.
• The burner drops out mid-run with no flame signal fault found at the flame detector.
• No control output to the gas valve or ignition transformer despite a call for heat.
• Erratic or intermittent sequencing that cannot be traced to the thermostat, detector or wiring.

• Confirm the existing control box carries the MMI810 Mod 13 reference and matches the control platform fitted to the appliance.
• Check the burner control model markings against the EOGB - Honeywell - Satronic range before ordering.
• Inspect the plug-in base, leads and earth connection for damage, as a poor connection can mimic a control box fault.
• Verify the fault is not being caused by the flame detector, ignition transformer or gas valve before replacing the control box.
