Inclined Glass Chimney — Illustrative Scenario from Vaishali
Customer's issue: Gesture control wave sensor stopped responding to hand gestures, requiring multiple tries to turn on.
Inspection: A thick film of vaporized tadka oil was coating the infrared sensor glass, attenuating the reflection signal.
Parts checked: Infrared emitter, photo sensor eye, ribbon connector, and front tempered glass.
Repair: Cleaned sensor prism optics with isopropyl solution, re-seated the display ribbon cable, and calibrated gesture sensitivity.
Estimated cost: Part cost: Nil | Labour charges: ₹350 | Total: ₹350
Final check: Single left-to-right hand wave powered the chimney on instantly, and right-to-left wave changed speeds reliably.
Curved-Glass Chimney — Illustrative Scenario from Vasundhara
Customer's issue: Both LED spotlight lamps went dark simultaneously while the blower fan continued running normally.
Inspection: High line voltage surge had damaged the internal 12V constant-voltage LED driver unit mounted above the motor.
Parts checked: LED spotlights, 12V LED driver transformer, lamp wiring, and control board light relay.
Repair: Replaced the blown driver module with a surge-protected 12V LED driver and re-terminated lamp connectors.
Estimated cost: Part cost: ₹300 (driver) | Labour charges: ₹250 | Total: ₹550
Final check: Both spotlights lit up brightly with steady, flicker-free illumination across the gas stove surface.
Pyramid Chimney — Illustrative Scenario from Raj Nagar Extension
Customer's issue: Suction dropped drastically; cooking smoke was filling the kitchen and blackened oil was dripping onto the cooktop.
Inspection: Baffle filters were completely clogged with several months of hardened tadka oil, and the grease collection groove was full.
Parts checked: Stainless baffle filters, oil collection channel, fan impeller blades, and duct opening.
Repair: Immersed baffle filters in hot chemical degreaser bath, scraped grease channels, and wiped motor casing.
Estimated cost: Part cost: Nil | Labour charges: ₹499 (deep clean) | Total: ₹499
Final check: Air velocity test showed complete smoke capture with zero oil dripping from filter edges.
Box-Type Chimney — Illustrative Scenario from Kavi Nagar
Customer's issue: Chimney motor failed to start upon pressing speed buttons; only a low buzzing hum could be heard.
Inspection: Motor start capacitor (6µF) had lost capacitance due to heat stress, preventing the motor from initiating rotation.
Parts checked: Start capacitor, motor windings resistance, shaft free spin, and control PCB relay.
Repair: Discharged and replaced the defective capacitor with a heavy-duty 6µF motor capacitor; checked bearing lubrication.
Estimated cost: Part cost: ₹220 (capacitor) | Labour charges: ₹250 | Total: ₹470
Final check: Blower motor started smoothly and spun up to full operating speed without any delay or electrical humming.
Island Chimney — Illustrative Scenario from Kaushambi
Customer's issue: Exhaust fumes were billowing back from the ceiling false-ceiling opening above the island cooktop counter.
Inspection: 6-inch aluminium duct pipe inside the false ceiling had disconnected from the roof cowl due to deteriorated PVC tape.
Parts checked: Ceiling suspension bracket, flexible aluminium duct, duct clamp, and external vent cowl.
Repair: Reconnected duct pipe using heavy-duty stainless steel worm-drive clamps and high-temperature aluminium foil sealing tape.
Estimated cost: Part cost: ₹350 (clamps & tape) | Labour charges: ₹450 | Total: ₹800
Final check: Full exhaust stream discharged outside through the external vent with zero smoke escape into the false ceiling.
Built-in Chimney — Illustrative Scenario from Shastri Nagar
Customer's issue: Chimney was overheating and automatically tripping off after just 10 minutes of cooking on the gas stove.
Inspection: Cabinet internal air passage was choked with accumulated lint and dust, trapping hot exhaust heat around the motor casing.
Parts checked: Thermal cut-off sensor, cabinet ventilation clearance, motor cooling fan, and duct connector.
Repair: Vacuumed cabinet enclosure, cleared lint from motor cooling fins, and improved heat dissipation spacing.
Estimated cost: Part cost: Nil | Labour charges: ₹400 | Total: ₹400
Final check: Chimney operated continuously for a full 45-minute cooking cycle without thermal shutdown.
Auto-Clean Chimney — Illustrative Scenario from Crossings Republik

Inspection: Multimeter testing revealed an open circuit in the thermal auto-clean heating band wrapped around the motor housing.
Parts checked: Thermal heating band resistance, thermal fuse link, control PCB relay, and oil collector cup.
Repair: Replaced the burnt thermal heating band with a compatible 120W heating element and replaced the inline thermal fuse.
Estimated cost: Part cost: ₹750 (heating element) | Labour charges: ₹400 | Total: ₹1,150
Final check: Auto-clean cycle warmed the motor casing properly and melted accumulated grease smoothly into the collection tray.
Filterless Chimney — Illustrative Scenario from Shalimar Garden
Customer's issue: Chimney produced an unbearable high-pitched scraping noise whenever the suction speed was set to Level 3.
Inspection: Solidified sticky grease on half of the high-speed centrifugal impeller blades was causing dynamic unbalance and housing scraping.
