Replacing Kitchen Extractor Fans: Quick DIY Guide

If your kitchen extractor feels weak, rattles, or just stopped pulling smoke away, it’s probably time for a swap. A new fan not only clears odors faster, it saves energy and stops grease from building up on walls. Below you’ll find the signs that scream for replacement, the tools you’ll need, and a simple step‑by‑step process that most homeowners can handle in an afternoon.

When to Replace Your Kitchen Extractor

Not every fan needs a brand‑new unit. Check these red flags first:

• Reduced suction: If the fan doesn’t pull steam away like it used to, the motor or blades are likely worn.
• Odd noises: Grinding, rattling, or buzzing noises mean bearings or the motor housing may be failing.
• Visible grease buildup: Heavy grease can clog the motor and cause overheating.
• Frequent tripping of the circuit: Electrical issues often hint at a dying motor.
• Age over 8‑10 years: Most kitchen fans last about 8 years before performance drops.

If you spot any of these, ordering a replacement is smarter than endless repairs.

Tools and Parts You’ll Need

Gather these items before you start:

• New extractor fan (match size and airflow rating of the old one)
• Screwdriver set (flat‑head and Phillips)
• Adjustable wrench
• Drywall or metal drill bits (if you need to adjust the opening)
• Safety goggles and gloves
• Electrical tape and wire nuts

Having everything on hand prevents interruptions and keeps the job smooth.

Step‑by‑Step Replacement Process

1. Turn off power. Switch off the circuit breaker for the kitchen extractor. Double‑check with a voltage tester.

2. Remove the old fan. Unscrew the mounting brackets, disconnect the wiring, and gently pull the unit away from the hood. Note how the wires are connected – a quick photo helps.

3. Clean the opening. Vacuum out any grease or dust left behind. This ensures the new fan sits flush and works efficiently.

4. Fit the new fan. Align the new unit with the opening, reconnect the wires using wire nuts, and secure it with the mounting brackets. Tighten screws evenly to avoid vibrations.

5. Seal and test. If there’s a gap around the fan, apply a small bead of silicone sealant. Turn the breaker back on and run the fan for a minute. Listen for smooth operation and check that airflow feels stronger.

6. Clean up. Dispose of the old unit responsibly, store tools, and wipe down the surrounding area.

That’s it – most people finish in under two hours. If you run into wiring mismatches or the fan won’t fit, it’s a sign to call a pro.

Cost and Maintenance Tips

A decent kitchen extractor ranges from ₹2,500 to ₹7,500 depending on brand and power. Installation fees (if you hire someone) add another ₹500‑₹1,500. To extend the life of your new fan, clean the filter weekly, wipe the outer hood monthly, and run the fan for a few minutes after cooking to clear residual steam.
