I have a Jenn-Air stove/range, both right hand burners are inop I've tested for voltage at the burner connector and getting zero volts. I'm trying to test the infinite switches but can't figure out how to get to the switches. I'm hesitant to remove the eight screws holding the drip pans in place affarid I may not be able to lift the pans back into place to reinstall the screws. Any help would be appreciated.

Thank you Simon for the response.
After thinking about this for a while if the switches check bad I'll replace them and then I will check the resistance between the switches and the connector that the cartridge plugs into, if the resistance is higher then a couple of ohms I will replace the harness but can't figure out how to get to the cartridge connector. Four screws will drop the pan under the cartridge but not sure if this will give me access to the connector.
Thank you in advance for your assistance.
