Common Refrigeration Issues & How to solve them

Monday, July 19th, 2021

Everyone nowadays has a fridge at home, and despite their ubiquity, they remain complicated beasts to understand. We tend to rely on them so much that even a few hours of malfunction can spoil weeks’ worth of food! To prevent this from happening, one of the best things you do is keep yourself informed about common refrigeration issues and how to solve them.

The most common refrigeration issues

Thankfully, our engineers at KES Facilities have a wealth of experience dealing with refrigeration issues, ranging from something as simple as a water buildup to more dangerous gas leaks. The issues that follow are the ones they run into the most, but if you come across anything else, don’t hesitate to call!

My fridge/freezer is too warm

Of course, the broadest problem also has the broadest range of issues that can cause it. It may be as simple as a misbehaving thermostat, which are notoriously sensitive; but it could also be a sealant issue, or worst case scenario, a refrigerant gas leak. While you may be able to test the thermostat and the door seals yourself (by trying to slide a £5 note through the door while it’s closed), a gas leak is a serious issue, and we recommend you contact a professional for it.

Unusual noises

Fridges and freezers are naturally noisy, but we get used to it. That’s why, when the familiar noise changes to something out of the ordinary, it may be a herald of common refrigeration issues.  An unusual noise may be the evaporator tray being askew, or worse, a sign of an impending compressor failure. The compressor is one of the most important and expensive parts of the fridge, and hiring someone to replace it might prove costly.

Water Build-up

Another annoyingly common refrigeration issue can be a build-up of water pooling at the bottom of your fridge. This is usually caused by the drain hole at the back (where the condensed water is meant to go) being blocked by dust or some other debris. You should be able to clean it yourself without too much hassle with a bit of cotton or some wire. No need to call an engineer for that one!

Other minor common refrigeration issues

You may also run into other minor issues that you can easily fix yourself. We mentioned a loose door seal earlier, but that is something you can fix yourself if you are willing to pull out the old one, buy a new seal from your manufacturer’s website, and install it. Similarly, if your fridge light has stopped working, your fridge’s manufacturer will be able to provide replacement parts, and they are easy enough to install yourself if you’re the least bit savvy.

If you run into any other issue, or simply want us to take care of the problem, give us a call! We’re always happy to help you.

Heat pumps: Renewable and Efficient regardless of season

heat pump

If you’ve been looking into heating or air conditioning recently, chances are you’ve heard of heat pumps.  While their ability to work regardless of season may seem magical to many, this guide will help you not only understand their arcane secrets, but also to make a decision: Is a heat pump right for you?


How do heat pumps work?

The simple answer is that heat pumps simply move the heat between your house and the outside. To get in more detail, they are divided into 2 parts: the condenser and the wall unit. The heat is absorbed by refrigeration coolant in the condenser (the bulky unit with a fan outside the house), then compressed and sent into the inside unit to release and heat indoors. In the hot season, the process is reversed, with the heat going from the inside to be released outdoors. This makes it so they work regardless of season, and are always useful to have around!


What makes heat pumps so efficient?

Unlike traditional heating or air conditioning units, heat pumps do not produce their own heat, but gather it from the air around them. This means that instead of needing electricity to both heat air, and circulate the heated air, all energy is spent on circulating heat. Because of this, heat pumps have been found to be almost 3 times as effective as traditional means!


Should you make the switch?

While you may be tempted after reading this article, you still need to consider the fact that installation and repairs tend to cost more on a heat pump than on a traditional radiator/air conditioner. On a daily basis, however, the pendulum swings back in favour of the heat pump, who will remain more efficient over time. Another thing to consider is that heat pumps can have trouble functioning in very cold conditions, but this only occurs at temperatures far below zero. Not likely to be a problem if you live in the UK!
