Fault is not with controls. On full bypass meaning thermistor unplugged from board, it will get below freezing. It should be capable of cooling 60 - 80 degrees below ambient air temperature. You need to fix airflow (venting requirements). Fiberglass bat insulation sides and top to have insulation close gap on sides and top helping to insulate box from exterior heat. Biggest issue is 5" gap at rear. You need to build an additional wall (box baffle) that closes that gap to 1" or less. Goal is rising airflow up at rear of refer is forced to pass across refer coils and fins to dissipate heat off them and escape out upper refer vent lid. Also use oem lid on roof. DO NOT USE AFTERMARKET CAMCO BRAND LID ON OEM DOMETIC BASE. They are very restrictive on dometics base and cause airflow problems. If CAMCO brand lid is used you must modify oem base vent to vent properly.
