High Temp
High engine temperature
Engine · Alarm
The red high-temperature icon means engine temperature exceeded the factory limit. Manual 100515 shuts the set down and disables restart. It says the cause can be excessive load or high ambient temperature, and it prints five owner steps.
Seen on: Champion home standby generators with the aXis controller covered by operator manual 100515. These are icon faults, not four-digit numeric codes.
Likely causes
- Too much load.
- High outdoor temperature plus restricted airflow.
- Debris inside or outside the enclosure.
Checks an owner can do
- Open the enclosure doors to move more air through the unit.
- Check the oil and add some if it is low.
- Remove leaves and debris from the interior and exterior so air can move.
- Wait until the engine is back in a normal range. The manual says this is generally about 30 minutes.
- Reset the fault, close the doors, and only then return it to service.
When to call a pro
If it overheats again after the enclosure is clean and the load is reasonable, contact Champion or a dealer. Do not run it with the doors open as a permanent fix.
