Troubleshooting Electrical Problems

After we moved into a house that seemed to have a lot of electrical problems, I had to learn how to troubleshoot things and fast. I learned how to flip the switch on my circuit breaker, deal with tripped GFCI outlets, and even how to rewire an outlet with the power off. It was a lot of work, but I was able to save a lot of money on professional services. However, after trying in vain to fix my circuit breaker on my own, I realized that I needed some help from an expert. A professional came out, took apart my panel and fixed everything. This blog is all about troubleshooting electrical issues and when to call a pro.

3 Probable Causes Of A Noisy Refrigerator


Your refrigerator is probably one of your most hardworking home appliances. Serious malfunctions could mean hundreds of dollars in spoiled food supplies and other kitchen inconveniences. If you have a noisy refrigerator, chances are that there are some components that aren't performing at their best. Read on to learn what could be causing that irritating noise from your appliance and how to fix the issue.

Worn evaporator fan motor grommet

This is a rubber lining that insulates the evaporator fan motor from the mounting bracket so as to absorb vibrations and help the appliance run quietly. With time, damage to this lining can leave it detached or cracked, increasing vibrations and causing loud noises from the freezer compartment. Check the evaporator fan to assess if the grommet is intact and have it replaced if it is worn out.

Evaporator fan motor

An obstructed or faulty evaporator fan motor can also cause a lot of noise to be created in the freezer compartment. This component is responsible for pulling air over the evaporator coil when the compressor comes on. If faulty, the freezer area will not only be noisy, but could be slow to freeze your ice due to the slow dissipation of heat from the compartment.

To inspect the fan and related components, disconnect the power and detach the evaporator fan cover. Check for any damaged or loose fan blades that could be vibrating vigorously and have them replaced. You should also examine the motor shaft for any obstructing debris and vacuum them out. Improved air circulation should keep the refrigerator quiet and also improve cooling performance. Try plugging the refrigerator on after these fixes to check if the noise has disappeared, but be careful not to touch live circuits to avoid electrocution.

If the appliance is still noisy, the issue could be caused by ice and frost around the fan and motor shaft area.

Condenser fan

If you have a frost-free refrigerator, chances are that is has a fan cooled condenser. The condenser fan circulates cool air over the condenser coil to keep the refrigerator cool and to defrost water in the drain pan.

Any dust particles in the fan and motor shaft could prevent the fan from running properly, leading to loud noises. Locate the fan at the bottom rear of the refrigerator and vacuum it to improve air flow. You should also check the fan blades for signs of damage and have them replaced.
