Emerson SureSwitch™ relay and CoreSense™ Protection module provide critical compressor protection by guarding against the most common sources of mechanical contactor failures – such as arcing, foreign objects, pests and brown-outs. Mechanical contactor upgrade with long life sealed switch, short-cycle and brown-out protection. SureSwitch functionality PLUS active system protection and diagnostics for Copeland Scroll™ single-phase compressors. ​ ​Reliable one million cycle rated switch backed with 5-year warranty ​ ​Same wiring as traditional contactor ​Adjustable short-cycle timer and brown-out protection ​Compressor shutdown when critical system faults are detected ​LED status and fault indication ​6 diagnostic codes with fault history Condenser Fan Motor FailureCondenser fan motors are a part of the condenser in an air conditioning system. The condenser fan motor commonly fails during the summer season.

see condenser fan motors failing due to normal wear, tear and high heat. have bearings and electrical windings that endure lots of usage. that can be oiled while others have permanently oil bushings, with either case both are subject to seizer, and with electrical windings, shorts and grounds are a common cause of failure too. Capacitors FailureA capacitor is an electrical device used to improve the operating characteristics of single-phase induction motors (compressors and fan motors). Most commonly the mircofarads in a capacitor fall below the rating which can affect the operation of the motors they assist. or 10% above the MFD rating are recommended they be replaced. Refrigerant LeaksAir conditioning systems contain refrigerant under high pressures. inferior welds and manufacture defects are the common cause for leaky systems. of refrigerant has many negative effects on an air conditioning system and can leadRe-charging a system with a refrigerant leak is NOT recommended.

Anytime a system is identified with a leak it should be immediately repaired to Compressor FailureThe compressor is a major component in an air conditioning system. that squeezes refrigerant gases from low to high pressures. The compressor has many operating components within it that make it subject to failure. system from leaks causes acid in the system which leads to compressor failure. condenser and/or evaporator coil leads to high head pressures, higher amps, higher heat and oil breakdown in the compressor. Overcharged systems lead to compressorMany problems can affect the operation of a compressor and result in failure. Contactor FailureA contactor is a device that connects the power supply from the main breaker panel to the condensing unit. The contactor has an electrical low voltage coil that is controlled by your thermostat designed to engage the contactor and connect voltage to the components of the condenser. The contactor has contacts that snap together

The main circuit board controls the electrical functions of the system. the relays within a circuit board fail due to normal wear, tear and high heat. other failing electrical components within the system can lead to the failure too. Spark/Glow Igniter FailureIgniters are responsible for lighting the fuel which heats your home. in the heating elements that create ignition can create lower temperatures and result in a failed ignition.

This is most commonly caused by normal wear and tear. the flame sensor can become dusty and affect its ability to operate properly causing the system not to ignite. 24-Volt Coil-Voltage F/L-Amp 30 Pole 2 Res 40-Amp Definite Purpose Contactor Definite purpose contactor 2 pole 30-Amp.
