As many of us are still working from home, visits to the fridge to see if new food has materialised in the last five minutes seems to be an inevitable part of our new working culture. But with all these extra visits, how do you maintain your fridge freezer and troubleshoot any issues? Find our quick and easy guide below to common fridge freezer issues that you may come across.


 Rust is commonly found on the external edges of fridge doors and bodies, often at the door hinges where humidity forms due to condensation. To rectify this, you can unscrew the hinges and remove them. Then you can use a rotary wire brush to remove all traces of rust and old paint. Next, apply an anti-rust primer before the final painting with spray paint. The hinges should then be lubricated and protected from any future rust by applying WD-40® Smart Straw Multi-Use, you can activate the Smart Straw applicator for a precise application to targeted areas or use the wide spray for greater coverage.


The seal of the fridge door is very important. After only a few years, the seals on the door could harden and then no longer be effective at sealing the two doors together. This can cause condensation that freezes and blocks the door. The ice must be removed with a wooden or plastic tool and the seal must be replaced. In some appliances this is quite simple, in others you may have to contact a specialised centre for refrigerator maintenance. To avoid this in future, you can treat the seal with water and vinegar, using a sponge and a cotton swab.


Fridges can be noisy and can sometimes hum. If you only hear noise when the compressor motor starts and stops, it means that the compressor shock absorbers have loosened: check the screws or locking nuts and tighten them after lubricating them with WD-40® Smart Straw Multi-Use or WD-40 Specialist High-Performance PTFE Lubricant. If the noise is continuous, you should check both the shock absorbers and the support feet, which may be poorly adjusted.

The coil

If dust has accumulated on the coil in the back of the fridge, you can remove it with a vacuum cleaner. If the dust is “greasy” and does not come away easily, we suggest treating it with WD-40® Specialist® Fast Acting Degreaser Spray which can dissolve it, allowing easy removal with a rag or paper towel.
