Quick answer: After a power cut, most appliances start again on their own once the power is steady. If one does not, first check the breaker panel: a tripped breaker or a tripped isolator switch is the most common reason. Reset it once. If it trips again, if the appliance hums but does not run, or if you smell burning, switch it off at the wall and call a technician instead of trying again.
What should I do during a power cut at home?
Switch off the AC, the washing machine, the oven and other large appliances at the wall or isolator switch. Keep the fridge and freezer doors closed. When the power comes back, wait until it is steady, then switch the large appliances on one at a time instead of all together.
Why is my AC not working after a power cut?
- The breaker or AC isolator has tripped. Look at the breaker panel and the isolator switch near the unit. Reset it once.
- The AC is waiting before it restarts. Many ACs have a built-in delay that protects the compressor after power returns, so the fan may run before cooling starts. Give it some time before you decide it is faulty.
- The thermostat or remote has reset. The screen may be blank or back on default settings. Check the mode (cool, not fan or dry) and the set temperature. Replace remote batteries if the remote does not respond.
- A part was damaged by a power surge. If the AC still does not start, the outdoor unit hums without the fan turning, or the breaker trips each time you switch it on, a part such as the capacitor, the control board or the compressor may need checking. See AC repair.
Why does my AC keep tripping the breaker after the power came back?
A breaker that trips again straight after you reset it is protecting the wiring. Don’t keep resetting it. Leave the AC off and ask a technician to check the unit and its electrical connection.
Why is my fridge not cooling after a power cut?
After the power returns, a fridge needs time to cool down again, and the ice maker needs even longer before it makes ice. Check that the plug and the socket are on, the display is not showing an alarm, and the temperature setting has not changed. If the light is on but the fridge stays warm, or the fan or compressor never starts, read refrigerator repair. For food safety after a long cut, follow official food-safety advice; when in doubt, throw it out.
Why is my CCTV camera offline after a power cut?
The recorder (DVR or NVR) and the router both need to restart before cameras show on your phone again. Check that the recorder and the router have power and their lights look normal. Then check that the recorder is still recording and its date and time are correct. If a camera stays offline or the recorder shows a hard disk error, see CCTV camera fixing.
Why is my Wi-Fi not working after the power came back?
The router and any extenders need to restart fully. Switch the router off at the wall, wait a moment, and switch it on again. If it keeps restarting by itself, or it shows “connected, no internet” for a long time, the router, its adapter or the line may need checking. See home Wi-Fi and networking.
When should I call a technician after a power cut?
Call a technician if a breaker trips again after one reset, you smell burning or see scorch marks, an appliance hums but will not start, the AC blows warm air for a long time, the fridge stays warm, or a camera or recorder will not come back online. Don’t open the outdoor AC unit or the breaker panel covers yourself.
