Thermo king code 94

[forestcat]

Hi guys, today I got a 94 alarm code on Thermoking SB3 unit. I looked up the discription and it says: Loader 1. Would anybody explain what is loader and should I be conserned with this code.
Thanks in advance

4 month it was no problem and now it showing up almost every day. it's not shutting down the reefer though. just alarm. any ideas of what this code means and what to do about it would be appreciated.

its the unloader valves on top of the compressor heads. This must be a old SBIII.
Check both the coils still work. I would assume Unloader one is the one closest to the front.

The reefer wouldn't be 'smart' enough to detect its not mechanically working, only not electrically working.

Thanks for the reply. It's a 2005 Great Dane trailer with ,I guess 2004 Yanmar engine in it. The name on the unit is Thermoking SB-310 with TK-486. Is it safe to continue driving with it till it gets home in 7-10 days or I have to find dealer and check it out?

SB3 and SB310 are two differnt worlds apart.
So if its a SB310 it will tell you what the code means on screen under alarms.'
There is no code 94 for this unit or any Thermo King unit anymore.

I see you double posted, here and reefertek
