How To Fix A Refrigerator That Runs Constantly
Posted on: 16 August 2017
A constantly running refrigerator isn't meaning you have to buy a new one. While a refrigerator must run on a regular basis to keep food cool, running constantly indicates a problem.
The main culprit behind a constantly running refrigerator is commonly the condenser fan, which pushes the hot air outside. It could be a number of issues that cause the constant running, so use this guide to diagnose the problem.
Regulate the Temperature
Temperature settings impact the running time of a condenser fan. The thermostat uses the readings from the freezer and refrigerator part to start and stop the unit.
Inspect the setting of the thermostat. If it is set too low, it may cause the fan to run constantly. Set the control between thirty-five and forty degrees (F) to attempt to make it stop running. Otherwise, the control may be defective. A new model needs twenty-four hours to adjust to room temperature and start cooling, so wait until the next day to see if it cools properly.
Humid climates could cause the unit to continuously run as well as sunlight from a window or heat from appliances. When the air cools, the unit should start running normal again.
Keep windows blocked from sun around the unit during warmer months to decrease the temperature. Opening the door frequently during a power outage increases the temperature inside the refrigerator, as well as putting hot foods in it.
Fix the Gasket
A gasket is the rubber piece along the edge of the freezer and refrigerator door that helps trap cold air. The suction of a seal often gets damaged from constant opening and closing of the door.
To remove the seal, disconnect the bolts with a wrench, and pull it off the door edge. Insert the new gasket into the grooves, and reinsert the bolts.
Clean the Condenser Coils and Fan
The fan on the unit can draw in dust that gets trapped on the condenser and coils, which causes it to run ineffectively. Put on work gloves to protect hands from sharp parts, and disconnect the power cord to the unit.
Detach the grille panel grille on the back or bottom of the refrigerator, look for the coils, then clean them with a vacuum that has a crevice attachment. Also, vacuum the condenser and the fan blades, or remove them and soak them in warm water.
Check the coils and condenser fan blades occasionally for dirt. Dirty parts can impact efficiency because the unit has to work harder to cool the room.
Check Parts for Continuity
Test the condenser fan, compressor start capacitor, and start relay with a digital multimeter. You may need to detach the components to test. Set the multimeter to "OHMs, and if it registers 'infinity", the parts need replacing.
