Possible Causes
Blocked intake or exhaust louvers, Failed cooling fan, Inadequate ventilation clearance around enclosure, Door safety switch misadjusted
How to Fix / Troubleshooting
Safety first: Do not operate the generator long‑term with doors open; this can be unsafe and affect cooling airflow.
- Step 1 – Inspect louvers and screens: Clean debris from air intake and exhaust louvers and any internal screens.
- Step 2 – Verify clearances: Ensure that vegetation, walls, or stored items are not blocking airflow around the enclosure per Multiquip installation guidelines.
- Step 3 – Check cooling fan operation: Confirm that the radiator fan runs at full speed with doors closed. Replace a failing fan motor or belt.
- Step 4 – Inspect door switches: Some units have door interlock switches. Adjust or replace a switch that incorrectly signals a fault when doors are closed.
