1. Check the connection of the connector.
2. Replace the IH power supply fan (FM7).

Intermittent E804 - 0007 was indicated at power on. A failure was detected at the IH Power Supply fan (FM7).

:
In one case, after inspecting the fan FM7 and in IO mode at address P028-bit 8 indicating "0", it was decided to replace the IH Power Supply and the fan FM7 at the same time to resolve this error code.
