What to do if Norlake Controller shows high room temperature HtA?
- KKimberly GonzalezAug 18, 2025
If the Norlake Controller displays a 'High room temperature HtA' alarm, it could be due to several reasons. The refrigeration might be insufficient, or the heat load could be too large; in both cases, check the system design to ensure it's adequate. Other potential causes include a failing compressor (replace it), evaporator fans not running (fix them), the door being open too long (keep it closed), or a coil iced-up (check for air leaks in the cold room walls).
