Troubleshoot Low Pressure Compressor [2012-02-06]


When your fridge has electricity, and is running, but the inside of the fridge is hot, check to see if there is a problem other than a broken Low Pressure Compressor. You should check to see if all the electrical controls of the fridge are working, as a compressor on a refrigeration unit rarely fails. Check to make sure you temperature control is in the correct position. Listen for fan noise to make sure the freezer fan is functioning properly. You will also want to listen for the compressor fan. The compressor fan is located at the bottom of the fridge, in the back where the compressor lives. If the freezer fan is running, the compressor fan is usually running at the same time. If the fans are not running, check that the fans are free from debris, and that dust is not clogging them.
1 Remove some recently added items if your compressor runs and does not turn off. Overloaded refrigerators, or refrigerators that have just been filled with an abundance of warm items, may struggle to cool down. The longer-than-usual cooling process will require your compressor to run continuously until the job is done. By removing some of the items in your fridge, you lighten the load and shorten the compressor run time.
2 Inspect the air filter connected to your condenser. This filter removes dust and debris from air entering your condenser. If the filter is clogged, there will not be sufficient air reaching your condenser, and your Low Price Compressor will run overtime to make up for it. The condenser may be located at the top or bottom, front or rear of your refrigerator, but is usually found behind a metal grill . Use your vacuum with brush attachment to clean away any dust or debris from the filter and the grill.
3 Check your home circuit breakers and fuses if your refrigerator compressor ceases to work altogether. Check that power is still being delivered to the refrigeration unit. If power is being delivered, and the compressor still fails to work, call a licensed refrigeration repair person to examine and repair the faulty compressor motor.
4 Check that all the refrigerator doors and drawers are properly closed and that the door liners create a tight seal around each opening if your compressor runs more than usual. Cold air leaking out, or warm air leaking in, can place more load on your Low Noise Compressor than normal and result in extended run times.
5 Move your refrigerator away from any walls or obstacles, and inspect the rear of the unit if you hear unusual sounds coming from behind or beneath the machine. If the noise you hear is originating from the rear of the fridge, the problem is likely the compressor. If your compressor is making strange or loud noises like rattling, call a licensed refrigerator repair person to perform the repair or replacement.
