GE Microwave factory default power setting m: JVM1540SM1SS June2007

Hello, new here, i have several vids on the above microwave on how to repair on my youtube called I Fix It All,, but i am stumped.

this is me... https://www.youtube.com/@ifixitall-24-7

Since i am fairly savvy to repairs, one part of this microwave is bugging me. What i want to do is change the default power level from PL-10 to PL-8. reason being is that this will lengthen the life of components / wear and tear. I am not very impressed at all with the airflow pattern the squirril cage fan provides so maybe one day i will add a fan that blows directly on my tranformer to help cool it off. this would have to be custom engineered though becuase any new airflow might negatively effect the oem placed limit / thermal switches which could be a bad idea.

I notice that the transformer is online for a tremendous amount of time before it cycles off and then back on. yet if i set the power level lower while in use i can hear the magnetic field making and breaking over the course of a heating cycle.

the primary purpose is this,,

If i use my microwave,, i want to run a lower power level by default but if i happen to "KNOW" i want to throw max power at an item, i will decide to up it to PL-10.

Ive just replaced my transformer and i have been through 2 caps so far since i got it in 07 at lowes. stand by,, gonna post another interesting topic but lets see who has cracked the oem code for the default power setting.

by the way,, there was NO accurate schematic for this model until i discovered the orig schematic was rolled up into the plastic keypad cover. I un rolled it, ironed it out and placed it in a different area for use later in a container i installed inside the mic with spare parts like micro-switches, diodes, limit switches etc. Im glad i found it because all the online diagrams were not matching my unit.
