Magnetron Replacement
Is it Worth the Cost?
Microwave not heating? The Magnetron might be dead. Find out if you should spend ₹3,000 on repair or buy a new unit.
Safety Warning: High Voltage
Never attempt DIY Magnetron replacement. The high-voltage capacitor retains a lethal electrical charge even when unplugged. The magnetron also contains beryllium oxide, which is toxic if broken. Always hire a certified technician.
The “Engine” of Your Microwave
The Magnetron is the heart of your microwave—it generates the energy that cooks your food. When it fails, the lights turn on, the plate spins, but the food stays cold.
In Mysuru and Bengaluru, replacement costs can range from ₹1,500 to ₹4,000. But is it worth putting that money into an old machine?
When to Replace the Magnetron
If your microwave is otherwise healthy (door closes well, keypad works), replacing the magnetron is a smart move.
- Symptoms: Loud buzzing noise, no heat, burning smell.
- Lifespan: A new genuine magnetron lasts 2-5 years.
- Value: Cheaper than buying a new Convection model.
Repair vs. Replace: Cost Comparison
Real-world estimates for Indian households.
| Option | Estimated Cost (₹) | Verdict |
|---|---|---|
| Magnetron Replacement | ₹1,500 – ₹4,000 | Best Value for expensive/convection models. |
| Buy New (Solo/Basic) | ₹5,000 – ₹7,000 | Better if you only reheat food. |
| Buy New (Convection) | ₹10,000 – ₹15,000+ | Expensive. Repair is usually better. |
The 50% Rule: How to Decide
If the repair cost is more than 50% of the price of a *new* equivalent model, don’t repair it.
Repair It If:
- Microwave is less than 5 years old.
- It is a high-end Convection/Grill model.
- The door, keypad, and body are in perfect condition.
Buy New If:
- Microwave is older than 8-10 years.
- The paint inside is peeling (rusting).
- You have other issues like keypad failure simultaneously.
Extend Your Magnetron’s Life
No Metal
Never put metal spoons or foil inside. Sparking kills the magnetron.
Don’t Run Empty
Running without food causes energy to bounce back and destroy the tube.
Cover Food
Prevents food splatter from burning on the waveguide cover.
