It’s the lower control board or speed sensor.

Not familiar with the model, but sounds like a board if it does not produce any error codes or is resolved by powering down.

Typically a dirty speed sensor will shut a machine down, because the speed the board and the sensor are not reading the same. Although this will often produce an error code, to be investigated.

Verify the safety key is present and functioning. Most machines use a magnet and any strong magnet will be enough to close the circuit.

Most treadmills meet there demise from a faulty lower control board under the hood. It can light and be mostly functional, but still have issues. Boards are not very cheap but are very easy to install.

Search for options on fitnessrepairparts.com.

Make sure to take an image of the original board to copy the wire location/connections.

Boards often go bad from an array of issues, but verify the condition of the underside of the walking belt is not black and the deck is not worn. Lack of lubricant and too much friction on the belt system usually overloads the board with heat and damages the board.

Front page of the manual has a contact for the manufacturer.

Warranty is on the back page.

Elliptical consoles come as completes, no harder to install then the original assembly

Most likely worn belt and deck, demise of almost every treadmill or the source of a blown lower control board.

Lube is usually every 150 mi or 6 months. Consumers rarely apply lube until its too late.

Putting lube on it does not resolve the damage to the deck. Look under the belt and see if the bottom of the belt is white. When a machine is run out/low on lube the bottom of the belt turns grey/black and the slippery board the lube is supposed help the belt run on gets rough.

Parts aren’t bad, couple hundred bucks. Shipping is brutal because the deck is a 40lbs 2’ x 4’ sheet of laminated wood. You would need to dismantle the machine down to the frame to install the deck or even the belt.

Could be way simpler, but start with the condition under the belt and the sliding deck.

Verify the wire harness to the console has continuity with a multimeter.

Very common for the harness to be damaged if disassembled and reassembled during a move.

Otherwise you would need to source a wiring diagram from mfg to see what the readings should be at the console connection.

If that all checks out then it most likely is the upper control board.

Just because the lower board is getting power doesn’t indicate it is functioning

It is either the resistance motor or the cable/activating arm is struggling.

The resistance is so high because the magnets that create the distance are very close to the steel flywheel.

You will want to open the machine up to view this area. The resistance motor and fly wheel are in very close proximity to each other.

To decrease the resistance the motor is activating a hinge to move the magnets further away from the flywheel. The magnets are typically behind a plastic cover inside the flywheel and will not be able to access them.

Open the machine up and investigate. The system is very basic and playing with it will give some insight.

Many times the console is not recognizing the safety key with this type of response.

Otherwise it is your upper control board or lower control board, most likely lower.

Double check the safety key

Most likely lower control board.

This is the circuit board under the plastic hood. Controls the elevation motor.

Unless the console has a stuck or faulty elevation button, then the console is not sending an incline signal.

When a board goes bad the machine will respond with erratic strategies, elevation on max is one example.

When the board is “bad”, it can also not tell it is out of control and won’t throw a code or signal to stop.

Boards are just plug and play, very easy to install. Take an image before removing the old board and you should be able to duplicate the harnesses.
