Common Symptoms of a Failing Contactor

• Homeowners in Calgary, Edmonton, Red Deer, Lethbridge, and throughout Alberta may notice the outdoor air conditioner will not start even though the thermostat is calling for cooling. A failed contactor is one of the most common causes.
• Air conditioning systems across the Greater Toronto Area (Toronto, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Ajax, Pickering, Whitby, and Oshawa) may produce a loud buzzing or chattering sound when the contactor coil begins to fail.
• During Alberta's hot summer months, pitted or burned contacts can prevent power from reaching the compressor, leaving the outdoor unit completely inoperative.
• Homeowners throughout the Greater Toronto Area may notice the contactor pulling in, but the compressor or condenser fan motor never starts because the electrical contacts have become badly worn.
• Air conditioners in Calgary, Edmonton, and throughout Alberta may repeatedly trip the breaker due to damaged or welded contactor contacts.
• Throughout the Greater Toronto Area, a contactor with worn contacts may cause intermittent cooling, where the air conditioner starts normally one cycle and fails the next.
• If your outdoor unit continues running after the thermostat has been satisfied in Alberta or the Greater Toronto Area, welded contactor contacts may be preventing the unit from shutting off.
• Excessive pitting, insect contamination, corrosion, or carbon buildup inside the contactor can cause unreliable operation for homeowners anywhere in Alberta, the GTA, or across Canada.
