Linear LDCO801 parts: distinguish 800/801 boards and backup hardware
For exact Linear LDCO801, the Nice/Linear 221377 Rev-S parts diagram has a dedicated LDCO 800/801 head-parts group. It lists BBU-compatible control board HAE00077, battery backup unit BBU, front cover HAE00051, main cover HAE00052, encoder board HAE00058, and motor HAE00057. The same parts list names wall station HAE00001 for LDO/LSO/LCO/800/801, while Wi-Fi wall station HAE00080 is a universal replacement for LDCO841/850/852/863B and Linear600, not 801. The official manuals index lists LDCO801 separately and links its installation and programming documents. Use the exact model label before choosing backup or control parts.
Safety boundary
- Use the exact model label and matching Linear owner/manual row; have a qualified technician verify internal parts and any BBU configuration.
- Do not open the operator, work on the battery backup wiring, capacitor, motor, logic board, or other internal electrical parts.
- Do not bypass safety beams or automatic reversal; stop use if entrapment protection is missing or fails the owner-level manual check.
Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.
Models explicitly covered
These model identities have the source evidence listed below. Read the part decision and suffix limits before ordering.
Required identifiers
- Complete operator model label exactly LDCO801
- Any existing control-board, battery-backup, or wall-station part number from service records or non-invasive label inspection
- Region and revision of the Linear replacement-parts list
Compatibility rules
- Rev-S page 2 identifies a parts group titled LDCO 800, 801; HAE00077 control board is marked BBU compatible, BBU is listed as a separate unit, and HAE00058 encoder board/HAE00057 motor are grouped for 800/801/841/850/852/863B.
- Rev-S page 2 lists HAE00051 front cover and HAE00052 main cover for LDCO 800/801.
- Rev-S page 4 lists HAE00001 Wall Station for LDO/LSO/LCO/800/801, but HAE00080 Wi-Fi Wall Station as a universal replacement for LDCO841/850/852/863B and Linear600 only; LDCO801 is not listed for HAE00080.
- The Linear manuals index has a separate exact LDCO801 row with installation and programming documents.
Never assume
- The Wi-Fi wall station HAE00080 fits LDCO801 because another LDCO model is listed as compatible.
- Every LDCO 800/801 part is universal across LDCO841/863B or suffix variants.
- A BBU-compatible board entry means a battery backup is installed or that the BBU itself is included in the board kit.
- Part-list presence proves stock, replacement supersession, or homeowner repair suitability.
Exact 800/801 group parts
- HAE00077: LDCO control board, BBU compatible (800/801).
- BBU: separate battery-backup unit listed for 800/801.
- HAE00051 / HAE00052: front and main covers for 800/801.
- HAE00058: encoder board and HAE00057: motor assembly, grouped for 800/801/841/850/852/863B.
Wall-station compatibility is narrower
Nice/Linear’s parts list maps HAE00001 wall station to 800/801, and separately maps Wi-Fi wall station HAE00080 to 841/850/852/863B and Linear600. The latter list does not include LDCO801.
Owner-safe boundary
These are identification references only. Board, motor, battery-backup wiring, and internal operator service should be performed by a qualified technician.
