What does code 89 mean on a Thermo King Reefer?
I recently just bought a 2007 Utility with a thermo king reefer. 1 minute after turning on the engine, I get alarm code 89 (ETV circuit), the temperature increases even though the set point should be decreasing the temperature. 5 minutes later, I get the code 21 (cooling system check). Right after I get the code 21, the engine shuts off.
Why does my Reefer keep showing ETV code?
From the sounds of it your system has a Freon leak and is out of Freon that’s why the temp is going up and it is showing ETV system because according to the computer your unit should be at certain temp by now and its not getting there so it throws that code also. Depending on where the leak is depends on how much it costs to fix.
