Eppendorf Centrifuge 5424 R Service | Manual

The most valuable part of the service manual is the Error Code Matrix. When the 5424 R encounters a failure, it displays an error on the digital screen (e.g., E-09, E-15, D-01). The user manual tells you to "Call service." The service manual tells you what voltage to measure.

Common error codes covered include:

Diagnosis from manual: The most common cause is a clogged air filter (user error), but if the filter is clean, proceed to Section 12.2 – Refrigerant Charge. The manual details that the 5424 R uses R-134a gas. You will need a manifold gauge set. Low-side pressure should be 15–20 psi at 25°C ambient. Low pressure indicates a leak in the condenser coil.
