Parallax 6345 power converter
We have had our 2002 Keystone Cougar 5ver (27 ft) for about a year. No issues with the Parallax 6345 power converter till the last time out. It is the original and is 16 years old.
Camping this last weekend, temps were in the triple digits for the four days at the RV park. We have a 30A shore power service and the power converter is 45A.
During the hottest times of the day, the main and A/C fuses tripped often. No bueno. Feeling these breakers, they were HOT. I did some research and found some guy camping in Arizona under similar temps had the same problem and when he directed a small fan at the open power converter in his trailer, the circuit breaker popping issue stopped. I directed a small fan at our power converter and the breaker issue also stopped.
I suspect either the fan is dead OR there is a 140 degree thermostat that kicks the fan on may have died. In any case, when I get the time, I will check the fan and probably replace the thermostat; might even put a small 110V muffin fan in to supplement cooling. The Parallax company seems to have morphed into Magnetek but they are selling the same units (6300 series) under both names.
If yours breakers pop under higher temps, this note may be of some use.
