Why Monsoon is Hard on Electronics in Mumbai
Mumbai's monsoon brings sustained high humidity (85–95% relative humidity), frequent power fluctuations, and occasional flooding in ground-floor areas. These conditions accelerate corrosion on metal components, cause moisture ingress in circuit boards, and create conditions for electrical faults. A few precautions taken in June can prevent costly repairs through September.
Air Conditioners — Keep Running, But Check the Outdoor Unit
ACs should ideally continue running through monsoon — they dehumidify the air and prevent moisture buildup inside your home. But the outdoor unit needs attention.
- Check that the outdoor unit drain holes are clear — blocked drains cause water to pool inside the casing
- Do not cover the outdoor unit with plastic covers or tarpaulins — it needs ventilation and the compressor generates heat that needs to escape
- If leaves or debris accumulate around the outdoor unit, clear them regularly — this is especially common in Mumbai buildings with trees nearby
- After a particularly heavy downpour, run the AC in Fan mode for 15–20 minutes before switching to Cool — this allows any moisture in the unit to dry out
- Have the drain pipe checked — blocked drain pipes cause water to drip from the indoor unit into the room
Refrigerators — Humidity and Compressor Condensation
- Keep the refrigerator 10–15 cm away from the wall on all sides — monsoon humidity reduces heat dissipation and the compressor needs airflow
- Wipe the rubber door gaskets weekly — monsoon moisture and mould can degrade the seal causing the compressor to work harder
- Check that the bottom drain hole (inside the fridge) is clear — it can get blocked with food particles, causing water to pool inside
- If condensation forms on the outside of the fridge door, it is normal in high humidity — wipe it down and ensure the door seal is intact
Washing Machines — Earthing is Critical
Washing machines use water and electricity simultaneously — a dangerous combination if earthing is not proper. Monsoon is when earthing faults become dangerous.
- Test your socket's earthing before monsoon with an earthing tester (₹200–₹500 at hardware shops) or ask an electrician to verify
- Never operate a washing machine if you feel any mild shock when touching the drum — disconnect immediately and call an electrician
- Keep the machine's exterior dry — wipe down condensation on the body after each use
- Front-loaders: check the door rubber seal for mould growth monthly — monsoon worsens this significantly. Run a hot water self-clean cycle once a month.
TVs and Electronics — Humidity and Surge Protection
- Install a good quality surge protector or voltage stabilizer on your TV — monsoon brings frequent voltage spikes from lightning and line disturbances
- If you live on the ground floor or near water, elevate electronics off the floor before heavy rain forecasts
- Do not turn on a TV or any electronics that have been exposed to water ingress — let them dry for 48–72 hours in a well-ventilated area first
- Avoid unplugging and replugging electronics during active lightning storms — surges travel through the power line at the moment of connection
General Monsoon Tips for All Appliances
- Install a good quality MCB (Miniature Circuit Breaker) and ELCB (Earth Leakage Circuit Breaker) panel — they cut power instantly on fault detection
- Keep a voltage stabilizer on premium appliances like refrigerators and ACs if your building has known voltage fluctuation issues
- Service all major appliances (AC, washing machine) before monsoon, not after a breakdown
- Silica gel pouches inside electronics cabinets and TV consoles absorb ambient moisture — replace them monthly
