Here is the latest on my fridge issue, hope my posting will help someone with a similar problem. I've learned a lot from this forum over the years so I'm hoping this posting will be of value in some way or another. I changed the thermistor yesterday, not that hard to move the fridge out a few inches. I tied a string to the old thermistor and taped the new one to the string and gently pulled it into place. However, the fridge continued to E-1 on electrical so it was not a thermistor issue. Called a major RV dealer to get them to trouble shot the issue, they were booked for 3 weeks. I spoke with Tyler at Tedco RV Supplies in Langley, B.C. and he advised to run electricity directly to the fridge by-passing the converter/charger. The fridge did not E-1 while connected for a few hours so the E-1 was a power supply issue. I have a Parallax 7355 unit and it required an updated lower section. I removed the old and installed new and so far it is working fine. It was a little harder than replacing the Thermistor, took 2 1/2 - 3 hrs.
