Marantec lists Synergy 370 at 850 N / 3/4+ HPCS with 9.3 in/s travel speed, 1,100 lumens and up to a 14 ft door. The shared Synergy 300 owner manual uses the same verified numeric fault-code language as the 380.
Confirm this is the opener you have
Use several source-backed clues together. The motor-unit label remains the strongest identity clue.
Use the full motor-unit label for model identity; do not identify from opener case shape alone.
This changes power-outage diagnosis and helps separate nearby models.
Use the active receiver or Learn-button generation before ordering a remote.
Model specifications that matter for troubleshooting
Remote / accessory evidence tied to this model
These rows come from the verified compatibility dataset. An added external receiver can still change the active radio path.
Exact model: current Synergy 300 / 315 MHz Marantec radio family
Marantec lists Synergy 370 in the 315 MHz family and current Synergy 300 comparison data.
Wall-control compatibility for this model
Wired controls follow the opener logic/control interface. Wireless wall consoles follow the active radio receiver.
Genie Universal Wireless Wall Console
Marantec frequency/receiver identity is the compatibility authority for this wireless accessory.
Verify: Genie's chart lists Marantec 315 MHz fixed-learn-code systems. Do not apply this row to older 40/390 MHz Marantec installations without an active 315 MHz receiver.
The 370 is the speed-focused Synergy 300 model
Marantec describes the 370 as its popular high-speed model and lists 9.3 in/s maximum travel speed. The 380 has the higher 1,100 N force rating but a lower listed 7.1 in/s speed.
Preserve that distinction in diagnosis: a 370 page should not inherit the 380's force figure simply because both use the same manual and diagnostic language.
The shared manual supports exact diagnostic routing
Marantec's Synergy 300 owner manual covers 360, 370 and 380 and publishes the numeric code table. That makes exact-model routing to the same signal family evidence-backed rather than a visual-generation guess.
Parts and model specifications still remain exact-model facts; only the verified code language is shared.
Common troubleshooting paths for this model
Route from the observed symptom or code. Do not use model identity by itself as proof of the failed part.
Numeric fault code
Use the Synergy numeric guide and preserve the displayed number before resets or settings changes.
Open the exact troubleshooting path →Code 10 or 28 while moving
Check for obvious obstruction and abnormal door resistance before any force/sensitivity work.
Open the exact troubleshooting path →Remote replacement
Use current Marantec 315 MHz compatibility and verify the active receiver path.
Open the exact troubleshooting path →Power outage
Confirm whether the optional backup battery is installed before treating outage behavior as a battery failure.

Motor-unit label
Photograph the full label showing Synergy 370. Use that label for manuals and model-specific parts.
Active receiver / Learn control
Record the Learn-button color or external receiver model separately. A replaced receiver can change remote compatibility without changing the opener model.
Exact symptom or signal
Write down the code, blink count, sensor LED pair, direction of travel and where the door stops or reverses before changing settings.
Door-system boundary
If the door is crooked, off-track, unusually heavy, or has damaged spring/cable hardware, stop opener troubleshooting and hand off the mechanical door problem.
Model-specific guardrails
- Synergy 370 is the faster current Synergy 300 model; do not copy the 380's 1,100 N specification.
- Numeric error meanings come from the exact shared Synergy 300 manual; its troubleshooting section is marked for professional installers, so settings/internal service remain outside homeowner decoding.
- A 315 MHz radio fact does not identify a diagnostic generation on its own.
- Stop for a heavy/off-track door or spring/cable damage.
Never use opener force or a safety-system bypass to compensate for a heavy, damaged, off-track or unbalanced garage door.
