Prep Table Rail Not Staying Cold
Here's what typically causes this, and why an on-site diagnostic — not a phone guess — is what gets you an accurate estimate.
Rail Gasket/Cover Issue
Cold air escaping from the top rail.
Evaporator Airflow
Restricted circulation to the rail.
Overloading
Product loaded above the fill line blocks proper airflow.
Why diagnosis matters: A symptom like this can trace back to several different root causes, and the fix — and its cost — depends entirely on which one it is. Roxly doesn't quote a repair price over the phone based on a symptom alone: a technician inspects the equipment on site, tests the likely components, and confirms the actual cause before giving you a firm estimate. That's what makes the quote accurate instead of a guess you find out is wrong after the work starts.
Is this different from the base cooling issue?
Yes — the rail and base can have separate airflow paths, so one can fail while the other works fine.
Does how I load the rail matter?
Yes — overfilling above the fill line is one of the most common causes of rail temperature problems.
