Why your Greenheck commercial kitchen hood is won't start
When a Greenheck commercial kitchen hood is won't start, here's what you'll usually notice: unit completely dead, no lights, no response. Door switch, control board, or power issue. Nine times out of ten it comes down to a failed start capacitor.
Most likely causes
- A failed start capacitor
- Faulty door switch or interlock
- A blown line fuse
- Tripped thermal protector
- A power supply or wiring fault
Known Greenheck commercial kitchen hood weak points
- grease accumulation in baffle filters, plenum and grease-duct
- upblast exhaust fan belt slippage, bearing wear and motor burnout
- insufficient make-up air causing negative pressure and backdraft
- control/DCKV sensor faults and fan-speed lockout
Quick check — and when it's not DIY
The one self-check that's actually worth your time: check the outlet and breaker, and confirm the door is fully closed and latched — many units won't start at all with a door safety switch tripped. Beyond that, if power and the door are both fine, the fault is in the control board or start circuit, and testing that safely means working inside a live electrical panel.
