What To Do"},"content":{"rendered":"\n

The most direct impact of a blackout is losing your fans, lights, and aircon. But there is another side effect. If you’re unlucky, a blackout can actually disable your fridge even after the power comes on. <\/p>\n\n\n\n

When you open your fridge door after a blackout has ended, the light may come on, but inside, it\u2019s warm. The ice is melting into a puddle, and yesterday’s cold leftovers now feel unsafe to eat.<\/p>\n\n\n\n

Why Fridges Can Fail After Blackouts<\/h2>\n\n\n\n

When power goes out and then comes back, it can cause a few problems. The voltage can dip really low or surge suddenly, like a rollercoaster for your electricity. These sudden changes put a lot of stress on your appliance’s electrical parts. <\/p>\n\n\n\n

Modern fridges, especially those with inverter technology, have sensitive control boards. These “brains” of your fridge can get fried by quick, strong electrical spikes, or “transient spikes” during power restoration.<\/p>\n\n\n\n

The most common failures after a blackout<\/h3>\n\n\n\n

One of the things that might break when the power goes haywire is the start relay\/PTC or the start\/run capacitor. If these fail, your compressor won’t be able to kick on, and you might hear a repeated clicking sound.<\/p>\n\n\n\n

Another one is damage to the main control PCB or the inverter board. These are the circuit boards that manage everything. If they get hit by a surge, your fridge can stop working completely. Sometimes, a safety device called a thermal overload protector can trip or weaken, also stopping the compressor from starting.<\/p>\n\n\n\n

In rare case, the power spike could cause your temperature display to go wonky, or the defrost control might get stuck “on,” or a fan could fail, or even a sensor could stop working correctly.<\/p>\n\n\n\n

What to Check in the First Hour of a Blackout Ending<\/h2>\n\n\n\n

The moment you discover your fridge has stopped working, here are a few quick things you can do in the first hour.<\/p>\n\n\n\n

Safety and basics<\/h3>\n\n\n\n

First, keep the fridge and freezer doors closed as much as possible. This helps to keep the cold air trapped inside for longer. If you have milk, meat, or other quickly perishable items, try moving them to a cooler with ice, if you have one.<\/p>\n\n\n\n

Next, check the power supply. Go to your electrical box (DB) and check the main switch or the specific breaker for your kitchen. Are all the switches flipped upwards? Anything dropped down? Is the MCB, RCD, or ELCB tripped? If it is, reset it.<\/p>\n\n\n\n

For a quick reset, unplug your fridge completely from the wall for about 10 to 15 minutes. This can sometimes clear minor electronic glitches. After waiting, plug it directly back into the wall socket.<\/p>\n\n\n\n

Sometimes the wall socket itself might be the problem. Try plugging another small appliance, like a phone charger or a lamp, into the same wall outlet to see if it works. Also, avoid using cheap extension leads for your fridge; it’s always best to plug it directly into the wall.<\/p>\n\n\n\n

Now, check your temperature setting. It’s possible that the power surge caused the temperature control to reset to a warmer setting (or a very high number). If it did, just set the temperature back to proper settings (roughly 3 degrees C for the main fridge, and -19 degrees C for the freezer).<\/p>\n\n\n\n

Finally, confirm that your fridge hasn’t accidentally switched into “demo” or “showroom mode.” This mode makes the lights work but stops the cooling. That’s what you see when you open a showroom fridge at Best Denki or Senheng, for example. If you see any display that says “OFF” or “DEMO”, you will need to figure out how to reset it for your brand of fridge.<\/p>\n\n\n\n

Listen, feel, and observe<\/h3>\n\n\n\n

If none of the above worked, then it’s time to dig deeper. Place your hand on the compressor at the back of the fridge. Is it humming and vibrating gently, which means it\u2019s running? Or is it completely silent, or perhaps very hot to the touch?<\/p>\n\n\n\n

If you hear a clicking sound every few seconds, that often suggests a problem with the start device or capacitor. These parts help the compressor kick into action.<\/p>\n\n\n\n

Next, open your fridge door and listen. Can you hear the interior evaporator fan running? And if you can access the back, check if the rear condenser fan is also working. Both need to run for proper cooling.<\/p>\n\n\n\n

Look at the fridge\u2019s display panel. Are there any error codes or flashing lights? If you see any, snap a photo of the display and also take a picture of the model label, usually found inside the fridge or at the back. This information will be super helpful later.<\/p>\n\n\n\n

Wait vs escalate<\/h3>\n\n\n\n

If you can feel the compressor running and it seems normal, give your fridge some time. It might take anywhere from 6 to 24 hours for it to get back to its stable, cold temperature. So, just wait and let it do its thing.<\/p>\n\n\n\n

But if, after 4 to 6 hours, there\u2019s still no cooling, or if the compressor isn\u2019t starting at all, that’s a red flag. In this case, it\u2019s definitely time to book a professional technician.<\/p>\n\n\n\n

When to Call a Pro Immediately<\/h2>\n\n\n\n

Sometimes, the signs are clear. If you spot any of these “red flags,” it\u2019s time to call a professional fridge technician straight away. Don\u2019t wait, because waiting might make things worse.<\/p>\n\n\n\n

Red flags<\/h3>\n\n\n\n

If you hear a repeated clicking sound but the compressor never starts, that\u2019s a bad sign. Even more serious is any burning smell or visible scorch marks around the fridge. These mean serious electrical problems.<\/p>\n\n\n\n

If your electrical breaker trips every time the fridge tries to start, something is seriously wrong. Don’t keep turning your breaker back off and on, as this will cause further damage.<\/p>\n\n\n\n

Also, if the compressor at the back is completely cold and silent, or surprisingly hot to touch, it needs immediate attention.<\/p>\n\n\n\n

Also look out for loud metallic knocking noises, heavy ice build-up where it shouldn’t be, or water pooling under the unit. These are all signs your fridge is in distress and needs an expert to check it.<\/p>\n\n\n\n

What your technician will ask for<\/h3>\n\n\n\n

When you call a technician, being prepared with information can help them diagnose the issue faster. They will definitely ask for your fridge’s brand, exact model, and age. When you book a fridge repair at Recommend.my<\/a>, you will need this info as well.<\/p>\n\n\n\n

Be ready to describe the symptoms clearly: what sounds you heard, any smells, and if there are error codes. Also, give them a timeline: when the outage happened, when power came back, and what you\u2019ve tried so far to fix it.<\/p>\n\n\n\n

Common fixes and ballpark costs (RM)<\/h3>\n\n\n\n

After diagnosing the problem, the technician will explain the fix and the estimated cost. Here\u2019s a general idea of common fridge repairs and their ballpark prices in Klang Valley.<\/p>\n\n\n\n

Keep in mind that these are estimates, and actual prices can vary. This depends on your fridge’s brand, the availability of parts (especially for specific models), and whether your warranty is still valid.<\/p>\n\n\n\n
