The refrigerator may arguably be the most critical appliance in your home. We rely on them all day, every day to preserve foods and keep them fresh.

There are scant few things that can actually contribute to an unusually noisy refrigerator, which is technically a good thing, since troubleshooting the problem doesn’t tend to take too long. You could be dealing with:

Fun (Not Actually Fun) With Refrigerator Fans

The majority of undue fridge noise comes as a result of a dirty or damaged fan. There are a few fans that could be at fault here, somewhat depending on the type of refrigerator you have. If your issue is indeed a fan, it could be the:

Strange Sounds at the Base of Your Refrigerator

A consistent rattling noise coming from somewhere near the bottom outside of your refrigerator is almost certainly a loose drain pan. This is a really obnoxious noise, but actually a very simple fix, since it usually only needs a quick tightening using the appropriate tool (screwdriver, hex key).

A Troublesome Refrigerator Compressor

Your compressor can be found on the back of your refrigerator. It is almost always a big black metal fixture; looks sort of like a funky space helmet. But if the sound is your compressor, you’re in for some fairly bad news, since it’ll need to be replaced. In some situations, it’s a better idea to just replace the refrigerator in total.

High temperatures cause conductors to expand and hence increase in length. The converse is true for low temperature conditions. The change in length varies from one conductor to another depending on its thermal expansivity. The length of copper conductors, for instance, changes by 5 feet per 1000 feet of length when the conductor temperature changes from 100 – 0°, while aluminum changes by about 7 feet. The length increases with increase in temperature and reduces with reduction in temperature.

This increase or decrease in length is of great concern when installing power transmission lines between poles and towers, or when installing other power connectors. There must be an allowance for this change in length since it can cause catastrophes if it’s not there.

Weather changes are associated with increase and decrease in temperature and thus affect power transmission lines and other conductors. However, change in temperature is only one factor that affects power lines. Below are the changes that occur to power lines and other conductors as a result of weather changes:

The amount of heat dissipated from power conductors is reduced during hot and calm weather conditions. Basically, if the temperature of air around the cable is low, more heat is lost from the cable to the air. If the air is already hot, the exchange of heat is lesser. This low heat dissipation causes the lines to overheat. However, the rise in conductor temperature (overheating) worsens when cables are transmitting too much power than required. The first effect of this increased conductor temperature is snagging, which is the downward bulging of the cable between two poles, caused by the increase in the length of cables.

Snagging is largest during extreme hot weather (largest increase in temperature) conditions experienced in summer. The increase in length results to downward bulging of the cable due to the effect of gravity. Excessive sagging is dangerous if it goes below the accepted height clearance – cables could come into contact with trees, buildings and other structures underneath, causing electrocution and fires.

Excessive sagging represent an added weight on the power line and this increase may cause the line to fail or to pull down weak poles and towers. The effects can be small but gradual and so the poles and towers will finally come down or require some adjustment/replacement after some time, which is costly. This sagging can also cause the lines to short out. Excessive sagging is also costly since it leads to increased electrical resistance. This means that a sagged power line transmits lesser current than it normally does, thus causing under-feeding of electrical equipment and industries. It is also costly and time consuming to rectify a sag.
