![]() That being the case, if the refrigerant is slightly acidic, use a suction filter dry-out kit to clean the system. The same applies if mineral oil was used to charge the compressor. This is because some burned out compressors are acidic (others like compressors with hydrofluorocarbon refrigerants and polyester oils are not acidic if burnt), especially if the refrigerants were chlorinated. Test the Refrigerant:Īn acid test has to be carried out on the refrigerant using the correct oil test kit to ascertain if it is acidic. There are 7 steps in compressor replacement: 1. ![]() However, the system needs to be cleaned out before the compressor is replaced. If a compressor grounds out upon testing, then it could be an indication that there are problems even though it may not indicate a burnout. Recirculation of the condenser air leaving the motor.High condensing pressure can also be linked to the following: However, if there is insufficient returning gas or improper airflow due to the high superheat value of the gas or charge loss, enough heat will not be removed from the motor. The returning gas (suction) cools the compressor, which helps to remove some amount of heat from the compressor’s motor. This causes a loss in its electrical resistance, a short to the ground, as well as an open winding.Īlso, high temperatures can cause the oil to break down, and as such, the lubrication provided will be insufficient, which increases friction within internal components. Here’s why: A high temperature removes the motor windings’ insulation. Increase in the Compressor Motor Windings’ Temperature:Īn increment in the temperature of the compressor’s motor windings or discharge area can lead to burnout. Some of these issues result from:Ĭompressor burnout can be attributed to the following: 1. Now work with us, and we’ll show you how to replace a compressor or clean a unit after experiencing a compressor burnout. In the same vein, a step by step guide to compressor replacement can help you remedy these problems – It will ensure that the replacement you’ve installed does not break down when you least expect. However, the repaired or replaced compressor could also fail after a few months if the source of the problem was not corrected properly.įor this reason, it is essential to know what can lead to compressor failure to ensure such problems are averted in the near future. ![]() With this guide, compressor replacement doesn’t have to ruin your businesses productivity. A failed compressor needs to be repaired or replaced to get things running smoothly.
