Mazda 6 sedan adverse effects of air-con and refrigeration

Posted by kobd2 kobd2
A model for KP-819 CA7201AT5 the 2013 Mazda six 2.0L new car or truck . Consumers report: In the event the vehicle air con , refrigeration procedure working inadequate.

Inspection and investigation : initially verify malfunction. Commence the car or truck , the correct open , air-con compressor electromagnetic clutch pull, measuring the temperature of the air con vent , the cooling result is indeed uncovered for being sbb key programmerpoor. Then link the manifold gauge air conditioning air-con program strain test . Motor idling , lower pressure is 120kPa, significant facet stress of about 1400 kPa, force is regular ; then the motor velocity enhanced to three 000 r / min, uncover air con significant and low facet strain isn't going to transform the fundamental exception . Suspected refrigerant scarcity , based on the specification of refrigerant recovery , re- filling the refrigerant into the regular sum (490g), then the exam was discovered , the increase from the motor velocity, the superior strain aspect stress remains lower . Has replaced the air-conditioning compressor , bmw icom review growth valve , with no outcome ; checked the air conditioning piping, etcetera. , there was no fouling phenomenon. Soon after additional assessment, the evaporator force pipe incredibly hot , low-pressure pipe warm. Verify this level, the only real fault is suspected condenser cooling impact brought about by inadequate , verify the condenser floor , thoroughly clean and totally free of dust , it appears which the failure was the condenser itself excellent problems.

Remedy: Change the condenser.
