A/C was not working although still had some charge. Removed compressor, drained oil, replaced with ester oil, flushed, vaccumed and charged with R 134. Still not cooling.
Technician performed analysis, says it needs new expansion valve (readily available and not expensive)
and: Evaporator temperature switch
or Evaporator Thermal switch.
Have searched usual parts sources and found this part OEM # 7307 1AA020 from one source at $ 73.00
Can anyone recommend an aftermarket part source that may be less expensive.
- I am not familiar with this switch, is it a common problem?
- Would a used switch be a good option?
- How do you test it?
Probably enough questions for this post. Any tips or information would be appreciated. John aka Kenneth
