FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can I confirm YORK 031-00940-001 is correct for my chiller?
Record the installed microboard and EPROM numbers, software version, chiller model, and serial number. Compatibility must be checked against the official replacement-selection table.
Can the existing EPROM always be transferred to YORK 031-00940-001?
No. Transfer it only when the official selection table permits that board-and-EPROM combination; some configurations require a specifically matched EPROM.
Can 031-00940-001 replace every earlier YORK microboard?
No. Replacement depends on the installed microboard and EPROM combination; verify both part numbers before ordering.
What must be recorded before removing the old board for 031-00940-001?
Record the old board number, EPROM number, software version, option wiring, jumpers, and chiller control configuration.
Why should the EPROM be handled separately during replacement for 031-00940-001?
The chiller application program resides in the EPROM, so electrostatic-discharge controls and correct orientation are essential.
Does 031-00940-001 require chiller commissioning checks?
Yes. After installation, verify displayed values, safeties, outputs, setpoints, communications, and the exact chiller sequence before service.
What information is needed when ordering YORK 031-00940-001?
Provide photographs of both labels, the EPROM number, software version, chiller model and serial number, and the existing control configuration.
