Whirlpool dryer not getting hot, despite everything testing correctly

I have a whirlpool Cabrio platinum wgd8500bc0 that gets warm but not hot. Unfortunately the usual fix of the thermal coils wasn’t the issue. I’ve tested all the components and they seem to be fine. I’ve replaced the coils, high limit thermostat, igniter and inlet thermistor regardless. It seemed like the inlet thermistor readings were off when it got hot, but that didn’t solve the problem. I also thought that maybe the high limit thermostat was tripping too early or taking too long to clear, but also not the problem. The dryer exhaust is clear and the pressure seems correct. The dryer ignites and burns for about 10 seconds, shuts off and takes too long to start the cycle again. I bypassed the high limit thermostat and it stays ignited, eliminating gas supply or valve issues, but if I pause the dryer it does not immediately re ignite. Also the dryer heats on manual cycles but is useless on automatic cycles.

I’m at a loss for where to go from here. I believe the moisture sensors only affects the length of the cycle and not the temperature. And I suppose it could be the board (it doesn’t have a mechanical timer), but not sure how to test it. The dryer does not display any error codes. Any info would be appreciated. Thanks
