Its making a ticking noise coming from the back of the fridge.
HI. There should be an access panel on the backside of your unit. gain access to the main control board, and observe the board, during actions. If the clicking is originating from the board, itself, simply replace the board. Now, if the clicking is originating from the compressor relay/overload, replace the compressor relay/overload start switch.
The compressor relay starts the compressor. A fault relay can result in the compressor failing to cycle on. The relay is accessed from the lower rear of the refrigerator. The compressor relay can be accessed by removing the terminal cover box. The cover is held on by tension or with a retaining clip. On some units. the relay may not be covered at all.(each model may vary). Beneath the terminal cover(if equipped), you will find the compressor relay, and the overload protector as well. The electrical terminals of the compressor motor are located here also. Remove the compressor relay by pulling it straight off from the compressor, gently. Pull the wire off of the side terminal of the relay. It is connected with a slip on connector. Firmly pull the connector, do not pull on the wire. You may need to use a pair of needle-nose pliers. Inspect the connector and terminal for corrosion. If either is corroded they should be cleaned or replaced. There are two types of relays you may encounter, wire coil and solid state. If the relay has an exposed wound wire coil it can be tested for continuity. Otherwise, the relay is of solid state design and requires specialized equipment for testing. Test the relay with a ohm(multimeter), for continuity. Set the meter to the ohms setting X1. With the relay upside down, place the probes into the terminals labeled "S" and "M"(the labeling may vary on each modle). The meter should display a reading of zero ohms, indicating continuity (or if using a continuity tester, it should light up). With the probes still in place, turn the relay over. You should hear the click of the magnetic switch engaging. The meter should now display an ohm reading of infinity (or the tester should not light up). Turn the relay upside down again, place the probe on the "S" terminal and place it on the side terminal labeled "L". The meter should now display a reading of zero ohms (continuity). Turn the relay over and the reading should change to infinity. With the relay upside down place one probe on the "L" terminal and the other probe on terminal labeled "M". The meter should display a reading of zero ohms. Turn the relay over and the reading will stay the same, zero ohms. Now, if the relay fails these described tests, it should be replaced asap.
