What it is

The EOGB relay is a 14-pin plug-in relay with a 230 V coil, designated MY4, and is listed against part number ZT570730. It is used on EOGB boilers, where it switches the electrical load for the appliance control circuits. Plug-in mounting allows the relay to be changed at its base without disturbing the existing wiring.

Signs this part needs replacing

  • The appliance does not respond to a call for heat or a demand signal
  • Audible chattering or buzzing from the relay
  • Intermittent operation that changes when the relay is disturbed
  • Visible burning, pitting or discolouration on the relay or its base
  • Burnt or acrid smell around the control area

Before you order

  • Confirm the existing relay carries the MY4 marking and has 14 pins
  • Check that the coil voltage is 230 V
  • Cross-check the part number ZT570730 against the removed relay or the appliance documentation
  • Inspect the relay base and socket for heat damage before fitting
