BOARD TERMINAL

Part R31107 is associated with the Board Terminal and is selected when the original part is no longer serviceable. It’s commonly ordered during repairs once the board terminal is identified as the root cause. Confirm the unit data tag and the old board terminal marking so part R31107 matches the correct revision. Functionally, it controls sequencing and electrical outputs for the machine; when it fails, the machine may not behave normally. When this control board starts to fail, you may see random shutdowns, no response at startup, and outputs not energizing. Because the board terminal influences how the unit runs, symptoms may worsen under normal load. Confirm the root cause first so the replacement actually solves the problem. To verify whether the board terminal is at fault, technicians may: verify incoming voltage and fuses; confirm sensor inputs and output calls. A confirmed swap to part R31107 helps reduce repeat downtime and recurring intermittent faults. For installation and ordering, keep the process straightforward. Order part R31107, install the board terminal carefully, and run a full operating cycle test after replacement. A verified part-number match for R31107 plus proper installation is the fastest route back to reliable operation. Keep the removed part nearby for a quick side-by-side comparison during installation. If the unit has multiple revisions, confirm the exact configuration to avoid mismatched parts. After the first test cycle, recheck hardware and connectors to confirm everything remains secure. After the first test cycle, recheck hardware and connectors to confirm everything remains secure. Keep the removed part nearby for a quick side-by-side comparison during installation. After the first test cycle, recheck hardware and connectors to confirm everything remains secure. Inspect related components so the new part isn’t exposed to the same stress that damaged the original.
