We just did an awesome update to the Advanced Refrigerator Repair Course.

We expanded and revised the instruction on sealed-system operation and diagnostics. We’ve got seven new presentations that explain how sealed systems move heat around and how to diagnose various sealed system failures. This deep understanding of how sealed systems work and fail will make you a true refrigeration troubleshooter. (Scroll down to see all that is covered.)

Whether or not you actually do sealed system repairs, you need to have a strong understanding of how the system works so you can accurately diagnose the problem.


Note to current students in the course

There were a number of changes. We rearranged some units, added some new ones, and replaced a few others.

If you are partway through the course, you might get a message that you can’t move forward until you’ve completed an earlier unit. Just look in the navigation bar on the left in the course at earlier Modules and you’ll see any units that you need to go back and complete.

If you have any questions or need any assistance, please contact us and we’re glad to help.
