After a power brown-out my Maytag Bravos dryer started beeping but will not turn on when a cycle is selected. Display panel lights up partially but the time display does not with the exception of the error code.  Ran the diagnostic and the error code is F-24.  Tech sheet says this means the  Inlet Thermistor is open.  I tested this and it has continuity but I replaced it anyway, unfortunately this did not fix the problem.  I also checked the outlet thermistor as well as the thermal fuse, all are good.  I also checked all the wiring from each of these and it appears to have good continuity.  Not sure where to go from here.  Could it be the  control board or the user interface board (display)?  Also checked the door switch and the heating coil just to be sure, they are good. Any help would be appreciated!

Need model number to give better advise. Using continuity to check is not accurate. You can check resistance at the thermistor and at the board. Checking at the board is to confirm the wiring.

The model is:  MEDB400VQ0. Thanks

Disconnect plug from main board and check resistances.

Am I checking the resistance in the wire housing specifically?  Therefore a bad wire housing since I already replaced the inlet thermistor?  Thanks

Checking the thermistors and wires at same time by check at the board. Also to check if you got the correct thermistor as inlet and outlet have different resistance ranges.
