We at Commercial Fridge Repairs pride to state that we are home to some of these best technicians whom you can opt for, to have the snag repaired most feasibly.
Now, speaking about fridge repairs, one of the most important chapters is checking the Positive Temperature Coefficient (PTC) Relay. PTC relay is a specific starting device, which works for the compressor of the refrigerators. The principle function of the PTC relay is to provide power to the start winding for a brief period to help to trigger the motor of the cooling compressor.
Now when the refrigerator stops generating cool air, it may be because of a malfunctioning PTC relay, which is also called the Start Relay. Here are the steps that our techies take to check the PTC relay.
Accessing the Relay
This is the first step, which the visiting technician for fridge repairs in Wetherill Park will take to check the PTC relay. They will unplug your fridge to make sure it is not being powered from any source. The duration of the test may vary. If it takes a shorter time then you can retain the foodstuff in the fridge, but if the situation is more complicated and the process is likely to take longer, then it is advisable to offload your refrigerator and stack the foodstuff somewhere else temporarily.
Now, the techies would look for the small access panel at the back of the fridge at the bottom end. They will use a screwdriver to take the holding panel off to access the relay.
Taking off the Plastic Lid
Now the techie will get to the compressor of your fridge, which comes in the form of a pretty fat black drum-like structure. They will get to one end of the compressor with a small box normally made of plastic, on that side with wires jutting out. The pro will pull it off the plastic cover and that will expose the relay.
Disconnecting the Wires
There may be a wire attached to a screw that is dug in the surface of the relay. The techie will loosen the screw with a screwdriver and pull the wire out of its place.
Removing the Relay
After taking the wire off, they will carefully pull the entire relay box out of its place.
Checking the PTC Relay
Now, the professional will start checking the relay. The pro will look for burnt marks around its ports or see if there is any charred smell in the relay. In case there are burnt marks, it is sorted and the relay has to be replaced.
Using a Multimeter to Read the Resistance
Now, the technician will use a multimeter to read the resistance to find whether it is working or not. The individual will put the probes in the M and S slots of the relay to check its open resistance. The reading should show ‘OL’, which means ‘Open Line’. This means there is an infinite extent of resistance on the two ports. If it does not show OL, it is most likely to show a reading of 0-1 Ω (ohm), which denotes the relay, is upside down.
Now they will keep the probers unchanged and will turn the relay upside down for checking whether it shows any difference in the reading. If the reading changes from OL to 0-1 Ω, then the relay is working fine. If the reading does not change from OL or shows a reading more than 1 Ω, then the relay has to be changed.
