Our lab refrigerator: Helmer - HPR120-GX is not holding temperature. A significant temperature change occurred on Saturday night/early Sunday morning that required all refrigerated vaccines to be moved offsite. It's unclear what caused the change, and I'd like to have the refrigerator reviewed for issues. Vaccines cannot be moved back onsite until a cause is identified.
Verified the temperature reading. Er04 points to communication issues on controller board. Reseated the cables. Let customer know the next step is board replacement (Part # 801015-1 cost $590.76).
🔍Technician Findings
Er04 on fridge, temperature range from 28 to -2.2 C.
