If you're having problems with your refrigerator, you may not need an expensive repairThe problem could be small and simple, and a minimum of work or a few refrigerator parts you install yourself could do the jobLet's take a look at some of the most common issues that people have with their refrigerators and how to solve them.

1The refrigerator is not running, and the light is not working
This problem means power isn't getting to the unit, and may be caused by a plug that's not in the outlet securely, a damaged electrical cord, or an outlet that's not providing powerBlown fuses and tripped circuit breakers are a common cause of problems, but the outlet itself could be damaged, tooCheck the voltage if all other systems are functioningIf you're using an extension cord, try removing it to see if the cord is damagedSometimes, the only refrigerator parts you need are a new plug or cord.

2The refrigerator isn't running, but light is functional
This is a little more difficult than a simple lack of powerCheck the temperature setting to see if it's been turned off or to zero, and be sure there is a space of at least three inches between the sides and back of the unit and the walls and furniture around itA one inch gap above the refrigerator is also required for proper air flow.

If these are all correct, you'll next need to clean the condenser coils carefullyIf this doesn't help, unplug the refrigerator and wait two hours, then plug the machine back inIf it starts, there's a compressor problem causing overheatingIt may also be necessary to test the temperature control, evaporator fan, defrost timer, compressor relay, overload protector and compressor motor to find out what's wrong.

3The refrigerator is working but the light isn't
In this case, you should try replacing the bulb and testing the switch to make sure both are working.

4The refrigerator runs, but isn't cold enough
First, check the temperature setting and make sure there's enough space for airflow inside and outside the refrigeratorLook for objects blocking the vents, test temperature control, and clean condenser coilsDoor seals or a faulty door switch may also be a problemLook for functional defrost heaters and timers, as well as testing the evaporator fanA clogged drain tube or a refrigerant leak may also be the source of your problems.

5Refrigerator is too cold
This should be a simple fix for most unitsFirst, check the temperature settingThen, try the temperature control if that doesn't work.

6The refrigerator makes a lot of noise
If you hear hissing and popping from a frost free unit, this is normalThe defrost heater causes this noiseIf other noises occur, make sure the unit is level, then check the drain pan and the fans for the condenser and evaporatorThe compressor mounts should also be inspected.

7The refrigerator won't stop running
This common problem could have a number of causesIf you just adjusted the temperature control, live in a humid area, or recently loaded the unit, the machine may run for over twenty-four hours before becoming entirely coolIf this time has passed or none of those circumstances have occurred, defrost the freezerCleaning the condenser coils, checking the door seals and testing the door switch may also be necessaryA new switch or other refrigerator parts can be a real help.
