DIY Controller for Purple Mattress

Hi all - I’m guessing this is going to be an easy one for most of you. I have a Purple Powerbase. Two linear actuators that raise the head and feet and two massage motors - one of each at the head - one of each at the feet. The controller keeps dying despite the bed being plugged into a battery backup. I’d like to just bypass their controller that eventually will not be covered by their warranty and just do it myself (with your advice). Any recommendations? Physical toggles are fine. All ideas are welcome. Thank you.

Linear actuator motors:
Input voltage: 24V DC
Max. load: 6000N (push)
Speed: 4.2mm/Sec
Duty Cycle: 10%
