Most Common Issues in Industrial Microwaves — And How We Fix Them in Ahmedabad

Introduction

If you're running a food business in Ahmedabad, your industrial microwave oven is probably one of your hardest-working appliances. From reheating ready-to-eat meals to defrosting bulk meats or prepping pre-cooked items, it’s a machine you simply can’t afford to lose.

But what happens when it starts misbehaving?

At Shree Shree Weighing Solutions, we specialize in repairing commercial and industrial microwave ovens for food service businesses across Ahmedabad and Gujarat. Based on hundreds of service calls, here are the most common issues we see — and how we fix them.

⚠️ 1. Microwave Not Heating

Symptoms:

• The light is on, the timer runs, but the food remains cold

• Fan might be running, but there's no internal heat

Likely Causes:

• Magnetron failure (the part that generates microwave energy)

• Diode or capacitor issues

• Faulty high-voltage transformer

Our Fix:
We inspect and test the magnetron using diagnostic tools, replace damaged components, and recalibrate your machine — usually the same day.

🧯 2. Burning Smell or Sparks

Symptoms:

• Burning plastic or electrical smell

• Visible sparks inside the cavity

Likely Causes:

• Damaged waveguide cover

• Food residue or grease build-up

• Short circuit in internal wiring

Our Fix:
We thoroughly clean the chamber, replace any burned-out insulation or waveguide covers, and fix damaged wires. Safety is our top priority.

🔊 3. Loud Humming or Buzzing Sound

Symptoms:

• High-pitched hum

• Vibrating or rattling noise

Likely Causes:

• Failing magnetron

• Faulty cooling fan or motor

• Loose internal panel or screws

Our Fix:
We isolate the sound source, tighten or replace components, and ensure all internal units are mounted correctly.

🔌 4. Microwave Trips Power Supply

Symptoms:

• Microwave cuts off abruptly

• MCB trips when machine starts

Likely Causes:

• Internal short circuit

• Faulty capacitor or diode

• Ground leakage in power supply

Our Fix:
We replace damaged electrical parts and test for safe operation. Tripping issues are especially common in older industrial units in places like Vatva and Odhav.

🧊 5. Door Won’t Close or Open Properly

Symptoms:

• Door latch doesn’t catch

• Machine won’t start due to door sensor error

Likely Causes:

• Worn-out hinges or latches

• Damaged door switch or sensor

Our Fix:
We realign or replace door latches and sensors. Door-related issues are quick to fix but crucial for safety.
