Major Issues in kitchen chimney
Â
Here are the common issues faced in kitchen chimneys and why they happen:
Â
Issue | Possible Causes | Solutions |
---|---|---|
Reduced suction power | Oil/grease clogging filters, long or bent ducts, motor wear | Clean filters regularly, service duct, check/replace motor |
Excessive noise | Loose ducts, faulty fan/motor, very high suction in small kitchen | Tighten ducts, service motor/fan, choose low-noise model |
Oil dripping from chimney | Oil collector full, filters choked | Clean oil collector weekly, clean/replace filters, use auto-clean model |
Smoke not getting absorbed | Low suction capacity, wrong chimney size, improper installation height | Upgrade to higher suction (1000–1500 m³/hr for Indian cooking), install 65–75 cm above stove, match chimney width with stove |
Chimney not switching on / power issues | Electrical fault, PCB damage, loose wiring | Check power supply, call service technician, replace PCB if needed |
Bad odor in kitchen despite chimney | Saturated filters, duct leakage | Clean/replace filters, check ducts for cracks/leaks |
Too much heat in kitchen | Low suction, undersized chimney | Upgrade chimney suction or size, improve ventilation |
Touch panel not working | Power surge, oil vapor on sensors, faulty PCB | Clean panel gently, use voltage stabilizer, replace PCB if damaged |
Auto-clean malfunction | Oil deposits on sensors, heating element failure | Clean sensors, service auto-clean unit |
High maintenance cost | Frequent filter cleaning (mesh), poor brand service | Switch to baffle/filterless chimney, choose brand with better service network |
Improper ducting issues | Long duct (>12 ft), too many bends, plastic pipe used | Use aluminum/steel duct, keep duct straight & short (<12 ft, max 2 bends) |
Excess vibration while running | Loose mounting, unbalanced fan | Check installation screws, service fan/motor |
Chimney trips MCB frequently | Overload on circuit, faulty motor, short circuit in wiring | Use separate MCB line, service/replace motor or wiring |
Grease accumulation around chimney | Poor filter efficiency, irregular cleaning | Clean filters regularly, use auto-clean feature, schedule servicing |
Chimney suction drops after few months | Motor clogged with oil, neglected servicing | Service motor annually, clean ducts and housing |

Low Suction Power (Smoke Not Getting Cleared)
-
-
Wrong suction capacity selected.
-
Clogged filters (oil/grease deposits).
-
Long or bent duct pipe reducing airflow.
-
Excessive Noise
-
-
High suction motor in small kitchens.
-
Poor ducting design (too many bends, small diameter).
-
Loose installation or vibration issues.
-
Oil Dripping from Chimney
-
-
Grease accumulation in mesh/baffle filters.
-
No auto-clean feature or irregular cleaning.
-
Electrical Problems (Not Switching On / Power Failure)
-
-
Faulty wiring, loose plug, motor burnout.
-
Power surge damaging PCB (control board).
-
Unpleasant Odor / Smoke Still in Kitchen
-
-
Ductless (carbon filter) chimneys not cleaned on time.
-
Duct leakage or improper sealing.
-
Excessive Heat in Kitchen
-
-
Wrong installation height (too high above stove).
-
Low suction capacity.
-
Touch Panel / Remote Not Working
-
-
PCB malfunction.
-
Grease/oil affecting sensors.
-
Frequent Maintenance Needed
-
-
Mesh filter models in heavy Indian cooking.
-
No auto-clean technology
-
Bad Installation Practices
-
-
Too many bends in duct → reduces suction.
-
Long duct (>12 feet).
-
Wrong height from stove.
-
-
Fix: Proper professional installation is critical.

-
Suction: 1000–1500 m³/hr for Indian kitchens
-
Size: Equal or larger than stove (60 cm / 90 cm)
-
 Filter: Baffle / Filterless with Auto-clean
-
 Noise: Below 58–60 dB
-
 Proper ducting (aluminum/steel, <2 bends, <12 ft length)
-

Ignoring Kitchen Size and Chimney Suction Power
-
Mistake: Choosing a chimney with low suction capacity for a large kitchen or high suction for a very small kitchen.
-
Impact: Poor smoke and oil removal, or unnecessary power consumption.
-
Tip: Match chimney suction power with kitchen size →
-
Small kitchen: 800–1000 m³/hr
-
Medium: 1000–1200 m³/hr
-
Large / heavy Indian cooking: 1200–1500 m³/hr
-
Wrong Chimney Size (Width)
-
Mistake: Selecting a chimney smaller than the stove/cooktop.
-
Impact: Smoke escapes and spreads in the kitchen.
-
Tip: Chimney should be equal to or slightly bigger than the stove width (60 cm for 2–4 burners, 90 cm for 3–5 burners).
Not Considering Type of Cooking
-
Mistake: Choosing low-capacity or filterless chimneys when doing heavy frying, tadka, or oily Indian cooking.
-
Impact: Quick oil clogging, poor suction, greasy kitchen.
-
Tip: For Indian kitchens → Prefer baffle filter or advanced auto-clean models.
Improper Installation Height
-
Mistake: Installing chimney too high or too low.
-
Impact: Low suction efficiency or discomfort while cooking.
-
Tip: Keep 65–75 cm distance between cooktop and chimney.
Neglecting Ducting
-
Mistake: Using long ducts (>12 ft), too many bends, or plastic/low-quality ducts.
-
Impact: Reduced suction, more noise.
-
Tip: Use aluminum or stainless steel duct, keep it short (≤9–10 ft) with minimal bends.
Overlooking Noise Levels
-
Mistake: Ignoring chimney noise during purchase.
-
Impact: Annoyance during long cooking sessions.
-
Tip: Choose models with noise levels ≤58 dB for comfort.
 Not Checking Maintenance Needs
-
Mistake: Buying a high-maintenance chimney (frequent filter washing) without considering convenience.
-
Impact: Poor performance if not cleaned regularly.
-
Tip: Go for auto-clean filterless chimneys if you want minimal maintenance.
Ignoring Kitchen Design & Aesthetics
-
Mistake: Selecting the wrong type (wall-mounted, island, or built-in) not suited to kitchen layout.
-
Impact: Wasted space, poor fit, reduced efficiency.
-
Tip:
-
Wall-mounted → Stove against wall.
-
Island → Stove in center.
-
Built-in → Modular kitchens.
-
Choosing Only on Price
-
Mistake: Going for cheapest option without checking suction, build, and service availability.
-
Impact: Frequent breakdowns, poor air quality.
-
Tip: Balance budget + performance + after-sales service.Not Considering Service Support
-
Mistake: Buying from brands with poor service in your area.
-
Impact: Difficulty in filter cleaning, spare parts, or repairs.
-
Tip: Check brand service availability in your city before purchase.
