BLDC Chimney Not Turning On — Troubleshooting Steps

You press the button or tap the panel, and your BLDC chimney stays completely silent — no hum, no lights, nothing. A BLDC chimney not turning on can feel more confusing than a regular chimney fault, because these motors behave differently from the older induction-style motors most people are used to. Here's how to work through it step by step.

BLDC stands for Brushless DC motor — a newer motor technology used in many modern Elica chimneys because it runs quieter, uses less power, and lasts longer than traditional induction motors. But BLDC motors rely on a small electronic control board to function, which means a "won't turn on" complaint is more often an electronics issue than a mechanical one. That's actually good news — it usually means nothing is physically broken, just that power or a signal isn't reaching the motor correctly.

⚠️ If you notice any burning smell, visible sparks, or a tripped circuit breaker along with the chimney not turning on, stop troubleshooting immediately and contact a technician — this points to an electrical fault that shouldn't be handled without the right tools.

Why a BLDC Chimney Not Turning On Happens — Common Causes

Before trying fixes, it helps to understand what's actually different about BLDC chimney faults compared to older motor types.

1. Power Supply Issue

This is the most common reason behind a BLDC chimney not turning on. Since the BLDC motor depends on a steady power supply to its control board, even a minor issue — a loose plug, a tripped switch, or a faulty socket — can stop the chimney from powering up at all, even though everything inside is fine.

Checking power supply for BLDC chimney not turning on

A loose plug or faulty socket is often the simplest explanation for a BLDC chimney not turning on.

2. Control Panel or Touch Sensor Fault

Most BLDC chimneys use a touch panel or electronic button rather than a mechanical switch. These panels can occasionally stop responding due to a software glitch, moisture on the sensor, or grease film blocking the touch surface — leaving the motor itself completely unaffected.

A touch panel that isn't responding is a very different fault from a motor that isn't spinning.

3. Motor Controller (Driver Board) Fault

The BLDC motor doesn't run directly off mains power — a small controller board converts and regulates the power sent to the motor. If this controller fails, the motor won't start even though power is reaching the unit and the panel lights up normally.

A faulty controller board is the one BLDC-specific fault that genuinely needs a technician's diagnostic tools.

4. Loose or Damaged Internal Wiring

Vibration over months of use, or a recent cleaning that disturbed a connector, can loosen the wiring between the control panel, controller board, and motor. This typically shows up as intermittent behaviour — the chimney works sometimes, then stops.

5. Tripped Circuit or Faulty Switch at the Wall

It sounds basic, but it's worth ruling out first: a tripped MCB, a faulty wall switch, or a socket that's lost power can look exactly like a chimney fault when the appliance itself is completely fine.

Troubleshooting Steps When Your BLDC Chimney Is Not Turning On

Work through these in order — most cases are resolved in the first three steps without needing a technician visit.

Check the wall switch and plug

Confirm the wall switch is on, the plug is firmly seated, and test the socket with another appliance (like a phone charger) to rule out a dead socket.

Check your home's circuit breaker / MCB

A tripped breaker for that specific kitchen circuit will cut power to the chimney entirely. Reset it if it's tripped and test the chimney again.

Wipe and dry the touch panel

If the panel has any grease film, moisture, or residue on it, clean it gently with a dry microfiber cloth and try again — touch sensors can misread input through a layer of grime.

Unplug, wait, and restart

Switch off at the wall, unplug the unit for about 2 minutes, then plug it back in and try turning it on. This resets the control board and resolves many minor software glitches.

Listen and watch closely during an attempt

Press the power control and note exactly what happens — do the panel lights come on at all? Is there any sound, even a faint click or hum? This detail helps a technician diagnose the fault faster over the phone.

Check for loose wiring near the control panel

If you're comfortable and the unit is unplugged, visually check that no wires near the panel or motor housing look disconnected or frayed — but avoid opening the motor housing itself.

💡 A quick way to narrow it down: if the panel lights up but nothing happens when you select a speed, the fault is more likely in the controller board or motor. If the panel itself doesn't light up at all, suspect the power supply first.

When a BLDC Chimney Not Turning On Needs a Technician

Because BLDC chimneys rely on an electronic controller rather than a simple mechanical switch, some faults genuinely need diagnostic tools and experience with this motor type specifically — not every chimney technician has worked extensively with BLDC units.

Panel lights up, motor doesn't respond Likely a controller board or motor wiring fault that needs testing with proper equipment.

No response at all, power confirmed working Could be a failed control panel or a deeper internal wiring break.

Works intermittently, cuts out randomly Points to a loose connector or an early-stage controller fault worth catching before it fails completely.

Burning smell or visible damage Stop use immediately — this needs urgent professional inspection, not DIY troubleshooting.

During a service visit for this complaint, a technician typically checks the power supply reaching the unit, tests the control panel response, inspects the controller board, and checks wiring continuity to the motor — in that order — before deciding whether a part needs replacement.

Frequently Asked Questions

The most common reasons are a power supply issue (loose plug, tripped breaker), a touch panel that isn't responding due to grease or moisture, or a fault in the motor controller board. Checking power first is the quickest way to narrow it down.

Not harder, but different. BLDC chimneys involve an electronic controller board, so faults are often diagnosed differently than in older induction-motor chimneys. A technician experienced with BLDC units can usually identify the cause just as quickly.

Checking the wall switch, plug, circuit breaker, and cleaning the touch panel are all safe to do yourself. If the issue persists after these checks, the fault is likely inside the controller or wiring and should be left to a technician.

Not necessarily. In many cases the motor itself is fine, and the fault lies in the power supply, control panel, or controller board rather than the motor winding itself.

This depends entirely on the actual fault found during diagnosis — a loose connection costs very little to fix, while a controller board replacement costs more. We always diagnose first and explain the issue before starting any repair.
