I recently replaced my IHKA module, symptoms were no cold air, no ability to adjust fan speed, fan still running after switch off, on occasions not lighting up, I’m sure there were others. Most things pointed to FSR which I replaced but didn’t cure. Bought a second hand IHKA on line and all is good.
On the regas front I’m not convinced they vacuumed the system enough, you must have said on the second regas that you only had it done a few days ago which should have prompted them to vacuum at least 30 minutes and then stand at least 30 minutes to see if it held the vacuum.
I would be amazed if a manafacturer was allowed to fit a PRV to the system and allow it to vent to atmosphere. My understanding is that if the pressure gets to high (not being cooled by the fan coming on)it switches the compressor off. ie cuts the power to the compressor clutch. If I’m wrong then please educate me.
