    some ol farts here will remember placing used filter driers inside their oven at home, to dry them out and re-use them on another job!

    Some will remember using a fractional horse compressor to evacuate systems prior to charging.

    NOTHING WRONG WITH THAT !! An electric oven will do a heck of a job, I advise against microwaves!

    Better go to the last paragraph of the following article before you attempt to reactivate a drier.

    In the 80's GE had in their service literature on domestic refrigerators to use the compressor to evacuate the system when changing out the compressor. No lie, I saw dozens of the service bulletins. I myself always opted for the vacuum pump and thermistor vacuum guage.
