GossTech Microwave Repair in Nairobi – Burning Smell During Use
Description: Smell burning from your microwave in Nairobi? GossTech repairs overheating, wiring, turntable, and magnetron issues for all brands & models across all Nairobi estates and border towns. Call 0723613664 or email info@gosstech.co.ke. Book online at www.gosstech.co.ke.
Why Your Microwave Smells Like It’s Burning — And How GossTech Fixes It
A burning smell during use is more than a nuisance; it’s a critical safety signal. Common culprits include carbonized food splatters, failing high‑voltage components (magnetron, transformer, capacitor), arcing at the waveguide cover or turntable support, a worn door switch causing arcing, a shorting control board trace, or motor windings overheating. Left unresolved, these can damage internal parts, trip breakers, or even pose a fire risk.
Good news: GossTech’s certified appliance technicians diagnose and repair burning‑smell microwaves across all Nairobi estates and bordering towns—same‑day in most areas. We service countertop, built‑in, solo, grill, and convection microwave ovens from all major brands.

At‑a‑Glance Diagnosis & Remedies
| Symptom you notice | Likely causes | What GossTech does | Typical turnaround |
|---|---|---|---|
| Strong burning smell, even when empty | Carbonized splatters on cavity/waveguide cover; arcing at mica cover | Disassemble, clean/replace waveguide cover, cavity restoration, dielectric test | Same day |
| Burning smell + buzzing or humming | Failing magnetron/transformer/capacitor/diode | High‑voltage (HV) bench tests, replace HV parts, align cooling airflow | 1–2 days (parts‑dependent) |
| Burnt‑plastic smell near door | Shorting door latch microswitch; melted interlock housing | Switch continuity tests, replace switches/latch assembly, safety interlock alignment | Same day |
| Burning smell + turntable stalls | Seized turntable motor, arcing at roller ring | Motor ohm test, replace motor/roller ring, lube‑free setup, cavity inspection | Same day |
| Burning smell only on certain dishes | Incompatible metal trim or chipped enamel causing arcing | User‑load assessment, cavity enamel touch‑up, owner education | Same day |
| Burning smell + no heat | Magnetron failure or blown HV diode/capacitor | HV diagnostics and replacements, recalibrate thermal cut‑outs | 1–2 days |
Safety note: Unplug immediately if smell is strong, smoke appears, or you hear crackling. Do not keep testing cycles—this can compound damage.

Common Microwave Problems We Also Repair
While this page focuses on burning smell during use, GossTech repairs every major microwave fault:
- No power / won’t turn on (fuses, line filter, door switches, power board)
- Not heating / weak heating (magnetron, diode, HV transformer/capacitor, inverter board)
- Sparking/arcing (metal splatters, chipped enamel, waveguide cover)
- Unusual noises (fan, HV buzz, magnetron rattle, turntable motor)
- Turntable not rotating (motor, coupler, roller ring, shaft)
- Control panel not responding (membrane keypad, touch IC, stuck keys)
- Display dead/dim, error codes, random resets
- Door not closing/locking (latch hooks, interlock switches, hinges)
- Stops mid‑cycle (thermal cut‑outs, overheating, door switch)
- Interior light/fan failures
- Broken glass tray/roller ring
- Bad smell after a surge (fried board traces, burnt wiring harness)
Root Causes of Burning Smell — Technical Deep Dive
- Carbonized residues: Food splatters dry into conductive carbon that arcs at the waveguide cover (mica) or cavity corners. Arcing leaves char marks and burnt smell even on later cycles.
- Waveguide cover damage: A burnt or oil‑soaked mica sheet allows microwave energy to arc, burning the cover and nearby enamel.
- Airflow/cooling issues: Blocked vents or failed cooling fan overheat the magnetron and transformer, producing a hot‑electrical smell.
- High‑voltage failures: A shorting HV diode or leaky capacitor overheats, often accompanied by humming and odour. Magnetron end bells can also overheat.
- Turntable motor stall: A seized motor or debris under the turntable coupler leads to friction heating and a rubber/plastic smell.
- Door switch arcing: Worn microswitch contacts arc at high current, leaving a sharp burnt‑plastic smell near the latch side.
- Wiring harness damage: Pinched or heat‑scorched wiring emits a persistent insulation smell and is a fire hazard.
How we fix it: We remove carbonized material, replace the waveguide cover, repair enamel touch‑ups, restore airflow, replace HV components, and realign door interlocks and wiring. Every repair ends with odour clearance runs and a safety re‑inspection.

| Inspect waveguide cover | Replace if stained, cracked, or burnt | Every 3–6 months |
| Keep vents open | Ensures cooling airflow to magnetron/HV | Monthly |
| Check turntable rollers/coupler | Reduces friction and heat build‑up | Monthly |
| Use microwave‑safe cookware | Stops arcing from metallic trims | Always |
| Deodorize naturally | Steam clean with water + lemon | Weekly |
Tip: If a smell persists after cleaning, stop using and call 0723613664. Persistent odour often means internal arcing or overheated components.

Frequently Asked Questions (FAQ)
1) Is a burning smell dangerous?
Yes. It can indicate arcing or overheating of high‑voltage parts. Unplug immediately and avoid repeated tests until a technician inspects it.
2) Can I continue using the microwave if the smell goes away after cleaning?
If light food odour disappears after a thorough clean and a lemon‑steam cycle, it’s usually fine. If the smell remains, that points to internal damage—book a diagnostic.
3) How long does a repair take?
Simple arcing clean‑ups and switch replacements often finish same day. Magnetron/HV parts may require 1–2 days depending on stock.
4) Do you repair built‑in and convection microwaves?
Absolutely—solo, grill, convection, inverter and built‑in units are all covered.
5) What if my model is old?
We’ll advise on parts availability. Where parts are EOL, we can offer compatible/OEM solutions or recommend replacement options.
6) Will repairs void my warranty?
If the unit is still under manufacturer warranty, we recommend authorized service first. Otherwise, our documented repairs and parts carry GossTech’s warranty.
7) Do you offer pickup and return?
Yes. We provide safe appliance transport for workshop repairs when needed.
