AC Electric element doesn't get hot....
Check that you have 120V AC power, then check the 5A fuse on control module (lower board).
If Power and fuse good......you can unplug AC heater element from board and plug it directly into AC power source. If element doesn't get hot.....BAD element 300W (check resistance across unplugged leads----40 ohms good)
IF element does get hot.....BAD lower board
IF element gets hot and fridge doesn't cool down (*test 24hrs)---cooling unit is BAD
Propane flame ignites and looks good..........how long did you operate before deciding fridge doesn't get cool??
Thermistor in food section senses temps.........thermostat uses that temp sensing to control electric & propane cycles.
T-stat turns them ON/OFF as needed to maintain temp set point
Fridge level, good ventilation............good flame no cooling effect (*test 24 hrs) cooling unit BAD
I take it you have good 12V DC power otherwise propane wouldn't lite/stay lit. Panel lights wouldn't be on. (3A fuse on lower board is for DC Circuit)
IF you have a light inside fridge....check that 'storage switch' is ON (side of lower board)
HERE is a pretty decent service manual that includes your S819.
It is sorta set up backwards.......contents/index pages at end etc.
BUT good info/test procedures
