Thanks for your ideas on demagnetizing.
The A/C system has been looked at by two different techs and my self. The pressure switch, klima relay, expansion valve, and speed sensor have been replaced. Also the compressor was resealed. I resealed the compressor myself and replaced the speed sensor. Thatís when I noticed the shaft was magnetized. The new speed sensor is not generating the required voltage.
It could be a defective speed sensor... It's a simple design... I can't see it not working. Any Ideas are welcomed. The shaft held strong on my screw driver. I thought it odd at the time
