Fridge not blowing cold air but running???
DO you have a residential fridge OR an RV electric/propane fridge?
Jacks, awning, slides (possibly fridge if RV type) don;t work.........ALL need DC power
Converter..
When plugged into shore power (or gen)
120V AC input..13.2V DC output
Supplies the DC System PLUS charges/maintains battery
No converter function batteery supplies DC System until it goes dead
Simple voltmeter test......
DC Voltage AT converter with AC power connected (shore power ON and Circuit breaker to converter ON)
13.2V DC output to battery (minimum)
DC Voltage check at battery S/B 13.2V DC (minimum also)
Converter DC output low....replace converter
Got good DC at converter but not at battery..then check for blown fuses in battery POS cable to converter
Hookup portable battery charger and SAVE battery from death by recharging it/maintaining charge until you replace converter
