Current Canadian generation covered by the newer manual family. Toro lists 418053488–999999999 separately and ties it to Form 3476-324 Rev A.
On a current Toro 39924, first decide whether the stop is an intentional motor timeout, a key-switch timing issue, a battery-state problem, or a load/protection event. Confirm the exact serial generation, make sure installed batteries provide at least 6.0 Ah combined, pause briefly in ACCESSORY when turning the key, then separate low charge, incomplete seating, temperature, high-amperage protection and moisture before treating the battery or machine electronics as failed.
The model number is not enough by itself. Toro’s current operator manual names model 39924 from serial 418053488 and up, and that serial boundary is the first diagnostic gate. Record the full model and serial before comparing symptoms because a procedure for an older Power Max e24 can look plausible while belonging to a different electrical or manual generation.
Before calling the machine dead, check the installed battery capacity. Toro states that the combined amp hours of all installed batteries must add up to at least 6.0 Ah or the machine cannot start. Model 39924 is shown with two 88660 battery packs, each rated 6.0 Ah / 324 Wh, but the starting rule is about the combined installed capacity, not simply the number of occupied battery bays. A partially inserted pack can also be missed: Toro notes that if the battery-compartment lid will not close completely, the battery is not fully installed.
A stop after the machine has been on but the auger has not been engaged can be normal behavior rather than a defect. In Toro’s troubleshooting table, the motor shutoff timeout is the first cause under “does not run or does not run continuously,” and the correction is simply to restart; the machine beeps to indicate that timeout. Preserve that timeline. A machine that times out while idle is a different case from one that dies the instant the auger meets a snowbank.
The key transition is another current-generation branch that generic battery articles usually miss. Toro says the machine may fail when the key is turned from OFF to ON too quickly. The correction is to turn the key more slowly and let it stop briefly in the middle ACCESSORY position. That same ACCESSORY position displays each installed battery’s state-of-charge and presence lights, so use it as an observation step before repeatedly cycling the key.
If the machine still will not run, follow Toro’s external battery branches in order: low charge, battery not fully seated, battery outside the appropriate temperature range, high-amperage protection and moisture on the battery leads. Toro gives 5°C to 40°C (41°F to 104°F) as the charge/storage range and instructs the owner to move a battery outside the appropriate range to a dry place in that range. Do not diagnose lithium-ion capacity from a pack that just came from extreme cold or heat.
A machine that stops only under very heavy snow can be reaching the high-amperage limit rather than exposing a bad controller. Toro’s corrective action for that branch is to cycle the key to OFF. The separate beeping table also lists overload and tells the operator to walk at a slower pace or break up a large pile before clearing it. A light-load retest after recovery is therefore more useful than repeatedly forcing the machine into the same dense bank.
Moisture is another observable branch. Toro lists moisture on the battery leads and directs the owner to allow the pack to dry or wipe it dry. Keep this check external: remove power and dry accessible battery/contact surfaces only. Do not open a pack, bridge terminals, spray conductive cleaners into connectors or defeat battery-management electronics.
Only after these user-level branches fail does Toro move to a damaged battery pack or another electrical problem, with the latter going to an Authorized Service Dealer. That is the correct parts boundary. Before buying batteries, a key switch or a controller, document which battery packs were installed, their indicated charge, ambient temperature, whether the timeout beep occurred, whether the fault appeared only under load, and whether the same fault repeats after a controlled restart.
Shut off the machine, remove the electric-start key, remove all battery packs and wait for all movement to stop before adjusting, servicing, cleaning or clearing the machine. Do not open, puncture, heat, jump or bypass a lithium-ion battery pack. Keep battery contacts dry and use Toro-specified Flex-Force packs and chargers.
Diagnostic sequence
Confirm 39924 and serial 418053488+
Why this check: Toro publishes a current manual specifically for this serial generation.
What to do: Read the model/serial decal and select the 418053488+ range in Toro Canada before applying this sequence.
What the result means: If the serial is earlier, stop and use the manual attached to that earlier serial range.
Verify enough installed battery capacity
Why this check: Toro states that installed batteries must total at least 6.0 Ah or the machine cannot start.
What to do: Check the battery model/capacity labels and make sure each chosen pack is fully seated and latched.
What the result means: If combined installed capacity is below 6.0 Ah, correct that condition before diagnosing a machine fault.
Use the key transition Toro specifies
Why this check: Turning the key from OFF to ON too quickly is a documented no-run cause.
What to do: Turn the key slowly and pause briefly in the center ACCESSORY position before continuing to ON.
What the result means: If the machine now starts, the observation fits the documented key-timing branch rather than a failed battery.
Read charge and presence before load testing
Why this check: ACCESSORY displays state-of-charge and battery-presence lights for the installed cavities.
What to do: Record which packs are detected and their starting charge before attempting the same test again.
What the result means: A missing presence indication or low charge should be resolved before replacing machine electronics.
Separate idle timeout from a load trip
Why this check: Toro lists motor shutoff timeout and high-amperage protection as different branches.
What to do: Note whether the machine had been sitting with the auger disengaged or stopped only when clearing dense snow.
What the result means: A timeout beep while idle calls for restart; a repeatable heavy-load stop calls for recovery and a lighter retest.
Normalize temperature and dry contacts
Why this check: Battery temperature and moisture on the leads are both official troubleshooting branches.
What to do: Bring an out-of-range pack to a dry 5°C–40°C location and dry accessible contacts before retesting.
What the result means: If operation returns after temperature/moisture correction, do not condemn the battery from the original event.
Escalate only after a controlled repeat
Why this check: The final user-facing branches are damaged battery or another electrical problem.
What to do: Retest with known charge, correct seating, normal temperature and light load; record the exact repeat behavior.
What the result means: A persistent failure under controlled conditions is appropriate evidence for battery substitution or authorized service.
Before you order parts
Do not buy a battery merely because the machine stopped once in a deep plow bank; overload/high-amperage protection is a documented branch.
Do not buy a key switch before trying Toro’s slower OFF → ACCESSORY → ON transition.
Do not call an undetected pack defective until it is fully seated and the lid closes normally.
Do not replace the machine controller based on a cold-soaked battery test; normalize battery temperature first.
Do not open a lithium-ion pack or bypass its protection system to perform cell-level diagnosis.
Retest without creating a second problem
Start with batteries whose combined installed capacity is at least 6.0 Ah, known charge, correct seating and normal temperature. Turn the key slowly through ACCESSORY, record the presence/charge lights, then start the machine.
Let the machine run briefly and engage the auger under a light, repeatable snow load. If it stays running under light load but stops only in a dense pile, preserve that load relationship instead of calling the machine generally “dead.”
If the fault repeats with normal temperature, dry contacts, adequate charge and light load, record model 39924, full serial, battery models, observed LEDs/beeps and the point of failure for Toro service.

Questions people get wrong
Why can a Toro 39924 look dead even with batteries installed?
One documented reason is insufficient combined installed capacity: Toro states the installed packs must total at least 6.0 Ah. A pack that is not fully seated can also prevent normal operation. Start with batteries whose combined installed capacity is at least 6.0 Ah, known charge, correct seating and normal temperature.
Does the key need to pause in ACCESSORY?
For this current manual generation, yes when diagnosing a no-run event. Toro specifically says to turn the key more slowly and stop briefly in the middle ACCESSORY position if OFF-to-ON was too fast. Turning the key from OFF to ON too quickly is a documented no-run cause.
What does beeping mean after the machine sat idle?
The current manual says a motor shutoff timeout can occur when the auger has not been engaged for an extended period; the machine beeps for that event and can be restarted. Toro lists motor shutoff timeout and high-amperage protection as different branches. A timeout beep while idle calls for restart; a repeatable heavy-load stop calls for recovery and a lighter retest.
When should I suspect an electrical problem instead of overload?
After adequate charge, correct battery seating, normal temperature, dry contacts and a light-load retest still produce the same failure. Toro then places unresolved electrical problems at the authorized-service boundary. The current troubleshooting table separately identifies motor timeout, key timing, charge, seating, battery temperature, high amperage, moisture, damaged pack and other electrical problems.
