VERIFIED
A message reading PO should be recorded exactly as it appears on the JennAir control. For a JennAir built-in refrigerator, the manufacturer’s documentation identifies PO as Power outage indicator; freezer temperature rose to 18°F (-8°C) or above.
How to interpret PO
Symptoms and information worth recording
Describe whether the product stopped mid-cycle, failed to start, changed temperature, made an unfamiliar sound, or displayed the message only once. These are observations to collect, not symptoms that every PO event necessarily causes. Note whether another code alternates with PO.
Checks you can make safely
For a refrigerator or freezer, document actual interior temperature if you can check it safely, whether doors seal correctly, and whether the alarm follows door opening or a power interruption. Follow the owner’s manual for any model-specific user reset or cleaning procedure. Keep perishable food safe and do not remove sealed-system parts or electrical panels. If the appliance leaks, smells of burning, sparks, or overheats, stop using it and arrange professional help.
What a technician needs to know
Record the exact model and serial numbers, a clear photograph of the display, the timing of the incident, recent interruptions to electrical power, and any normal owner-level steps already taken. A technician can compare these details with model-specific diagnostics and explain the proposed repair before parts are recommended.
JennAir service in San Francisco
For a built-in appliance in San Francisco or the surrounding Bay Area, describe any access requirements, such as a condo service elevator, a narrow kitchen passage, or parking restrictions, when requesting an appointment. The visit window should be confirmed in advance. Diagnosis comes before parts are recommended; a written estimate is presented before work, and no repair goes ahead without customer approval.
Frequently asked questions
No. The same characters may be used differently across appliance families and model generations. The complete model number and the manufacturer’s documentation determine the appropriate interpretation.
That depends on the symptoms and the model’s instructions. Stop operation if you notice leaking, overheating, unusual electrical behavior, or another immediate hazard. Avoid repeatedly running a malfunctioning unit just to reproduce the message.
Take a photo of the code, find the model label using the owner’s manual, and make a short note of when the alert appeared. Do not dismantle the appliance to investigate.
Model compatibility: JennAir reuses codes across series and model years, so PO may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
