LiftMaster 10-10315M1 E-Box, MT
The LiftMaster 10-10315M1 is an electrical box replacement part for select LiftMaster MT medium-duty trolley commercial door operators. In a commercial trolley operator, the e-box houses or supports key electrical components and provides the area where control wiring, limit wiring, accessory circuits, and operator electrical hardware are organized. This listing is for the MT e-box part number, not a universal box for every LiftMaster medium-duty model.
The MT operator family is used on sectional overhead doors where a trolley rail drives the door from the header area. Because MT operators can be configured differently by voltage, phase, logic generation, and accessory wiring, the e-box part must be matched by the operator parts diagram instead of appearance alone. A box from another medium-duty family can look similar but may not match the correct mounting, wiring layout, internal component arrangement, or cover style.
This product page should help customers understand that 10-10315M1 is model-family specific. It is commonly cross-referenced as 10-10315 or 1010315, but those related numbers should be treated as search and cross-reference numbers, not proof that every similar e-box is interchangeable. If the existing label is missing, the safest path is to identify the operator model and serial information and compare it to the LiftMaster parts breakdown.

Technician Note
For LiftMaster medium-duty operators, the electrical box should be selected by model family and diagram. The replacement parts guide also shows that complete electrical box replacement kits may be model-prefix specific, so a bare e-box number should not be treated as a universal kit.
Before Ordering
- Confirm the operator is an MT medium-duty trolley model.
- Check the existing e-box label or parts diagram for 10-10315M1, 10-10315, or 1010315.
- Confirm the voltage and phase of the operator before any electrical repair is started.
- Check whether the needed item is the e-box itself, a complete e-box kit, a cover, a wiring harness, or a logic board.
- Inspect connected wall stations, safety devices, limit wiring, and accessory wiring before reconnecting the operator.
Professional Advisory
Electrical box replacement can involve high voltage and control wiring. A qualified commercial door technician should disconnect power, label wires, follow the LiftMaster wiring diagram, and test the operator, limits, brake if equipped, wall controls, radio controls, and required safety devices after service.
Questions & Answers
What operator family uses 10-10315M1?
The 10-10315M1 is an MT electrical box replacement part used with select LiftMaster MT medium-duty trolley commercial door operator applications.
Is this the same as a logic board?
No. This is an electrical box or e-box part, not the logic board by itself. Internal boards, switches, harnesses, and other control components must be matched separately.
Are 10-10315 and 1010315 related numbers?
Yes. Common references list 10-10315M1 with related numbers 10-10315 and 1010315. The exact suffix should still be matched to the parts diagram.
Can this be used on MJ, MH, or MHS operators?
Do not assume so. The row and supporting references identify this item for MT trolley operators. MJ, MH, MHS, BMT, and MGJ electrical boxes may use different kits or model-prefix assemblies.
Why does voltage matter for an e-box?
Commercial operator electrical boxes may vary by model, voltage, phase, and control logic. A box that looks similar may have different internal components or wiring provisions.
