not sure where r162 is but there is a p16-2 where power from the transformer enters the board on a blue wire. Power leaves board at the connector on 2 red wires pin 16-5 and pin 16-7 and reenters on the blue wires pin 16-2 and 16-3
To test the transformer you should get 75Ω-95Ω on the red wires and 2Ω-4Ω on the blue wires.

based on the color bands... red red gold gold.... the resistor is 2.2Ω with 5% tolerance
(first digit red = 2 , second digit red =2 that's a value of 22. the first gold represents a multiplier of .10 so the value is now 2.2Ω. The second gold represents a Tolerance of 5%)

So let's recap:
- you have a valid 120vac power supply to the board
- you're getting about 20vac out of the secondary winding on the transformer. If the rectifier on the board is good, then it's converting that to about 12vdc for its own use.
- buttons beep when pressed but no display and no oven function, either oven.
Does this correctly sum up where we are?

(Yes) except I have not performed any tests on the rectifier board - you're getting about 20vac out of the secondary winding on the transformer. If the rectifier on the board is good, then it's converting that to about 12vdc for its own use.

Let me know if I need to test the 'rectifier' and if so what diagnostics need to be performed.

If there's a problem with the rectifier or any other part of the main control board, your best bet is to contact Fixyourboard.com and see if they can repair the board for you.

A damaged suppressor board is easy enough to spot. If it's not fried, it's good. Sounds like your control transformer checks out ok too. Concur with Master Samurai and Brother Durham about reconditioning the microcomputer.
