Identifying Bad Compressor Ohm Readings
To identify bad compressor ohm readings, you need to first understand that the ohm readings are a measure of the resistance encountered by the electrical current flowing through the compressor’s motor windings. This resistance is influenced by several factors, including the condition of the motor windings, the temperature, and the material of the components.
The ideal way to start is by referring to the manufacturer’s guidelines that came with your appliance. These documents often provide the standard ohm reading range for the specific appliance. You can generally find this information in the user manual or on the manufacturer’s official website.
Once you have the standard range, use a multimeter to measure the ohm readings. To do this, ensure that the appliance is turned off and unplugged to prevent any electrical accidents. Set the multimeter to the ohm setting, then connect its probes to the terminals on the compressor. Note down the readings.
Bad readings are those that fall outside the standard range stipulated by the manufacturer. A significant deviation from the standard range could indicate a myriad of problems such as damaged motor windings, electrical imbalances, or even a complete system failure.
It’s essential to note that extremely low or high ohm readings indicate serious issues. Extremely low readings might indicate a short circuit, while extremely high readings could signify an open circuit or burnt windings, both of which are severe issues requiring immediate attention.

Steps to Correct Bad Compressor Ohm Readings
Correcting bad compressor ohm readings can be a systematic process. First, ensure that the appliance is completely turned off and unplugged to ensure your safety during the procedure. It’s crucial not to skip this step to avoid electric shocks or other accidents.
Begin by visually inspecting the compressor for any obvious signs of damage, such as burnt areas, exposed wires, or strange smells that could indicate a burnt motor. If you observe such signs, it usually means that there is a serious issue at hand.
If no visible signs are present, the next step is to check the electrical connections and the motor windings. Using a multimeter, check the resistance on each winding and compare it to the standard range provided by the manufacturer. If the readings are off, it indicates an issue with the windings.
Should you find discrepancies in the ohm readings, it is advisable to consult with a professional technician to further diagnose the problem. They might recommend solutions such as rewinding the motor, replacing faulty electrical components, or, in severe cases, suggesting a full compressor replacement.
It is important to note that if you are unfamiliar with electrical systems and appliances, it is always better to call a professional technician right away rather than attempting to fix the issue yourself, to avoid exacerbating the problem or causing harm to yourself.
