The refrigerator is likely to be amongst the most used appliance in your kitchen. It’s something that you most certainly need every day, all through the year. However, as unfortunate as it may be, your fridge might be running for a long time than it is actually normal. In cases of the kind you shouldn’t give up – it’s not something that serious. There are a few components which might be malfunctioning and you can take them out and replace them with new ones to prolong the life of your appliance.
Of course, the number of things which could have gone wrong is significant, but it is important to have look at the most common problematic components that you have to consider.
This could either be a regular electronic or mechanical timer which is adaptive. Both are usually used in order to start the important defrost cycle. They turn on the heater at frequent intervals of time and for the necessary duration. Mechanical defrost timers are far more commonly installed and they would usually activate the defrost cycle about every other 8 to 9 hours of running compressor time. This is normally going to take place once every two to three days. This cycle should be finished in about thirty minutes.
If this device malfunctions, logically, you would either end up with a frozen fridge or with a melted one –depending on whether the timer is working excessively or not enough. Both cases are devastating for the stored food so immediate replacement is necessary.
As we mentioned above, the timer is responsible for the activation of the defrost heater but if the latter isn’t functioning properly the results are going to be the same. This is a component which is located next to and below the evaporator coils. In most cases, this is usually controlled through the timer. It’s usually encased in glass and it has wire leads perfectly insulated.
Thermostat for Defrost termination
This component is situated on the evaporator coils and the main purpose is to switch off the defrost heater as soon as it reaches the necessary and designated limits. This thermostat is generally wired in a range of series connected to the defrost element and it is most commonly an open circuit about 35 to 47 degrees (F). It is better to call in the professionals if you are unsure of how to go about the repairs on your own.
In any case, if you have an issue with any of the aforementioned components, your fridge isn’t going to work as intended. This is going to have an impact on its performance and on your food that you store within it. Therefore, calling a professional appliance repair expert is absolutely imperative. It’s not advisable to attempt to solve these issues on your own so make sure that you get in touch with experienced specialists.
