How To Fix Weslo Treadmill

If your Weslo treadmill has stopped working, you’re probably wondering how to fix Weslo treadmill problems yourself. This guide will walk you through the most common issues, from a dead machine to strange noises, with clear steps to get you running again.

Before you start any repair, safety is the most important step. Always unplug the treadmill from the wall outlet. This prevents any chance of electric shock or the belt suddenly moving while you’re working on it.

Common Weslo Treadmill Problems and Solutions

Most issues fall into a few main catagories. Identifying the symptom is the first step to a fix.

Treadmill Won’t Start or Power On

This is a frustrating but common problem. The solution often involves checking a simple series of connections.

Check the Power Source: Ensure the power cord is firmly plugged into a working outlet. Try a different outlet or a lamp to test the circuit.
Inspect the Safety Key: The magnetic safety key must be fully inserted. Look for any damage on the key or the post it attaches to.
Examine the Circuit Breaker: Many Weslo models have a reset button or circuit breaker on the motor hood or near the power cord. Press the reset button.
Look at the Wiring: With the power disconnected, check the connections from the power cord to the console and the safety key switch. A loose wire can stop everything.

Treadmill Stops Suddenly During Use

If the treadmill quits while you’re on it, it’s often a overload or safety issue.

Overheating Motor: The motor may have an internal thermal fuse that trips. Unplug the machine and let it cool for 30-60 minutes before trying again.
Faulty Safety Key: The key might be making intermitent contact. Try removing and reinserting it several times.
Low Household Voltage: If other lights dim when the treadmill starts, your home’s voltage might be to low. This can cause the motor to cut out.

Treadmill Belt is Not Moving Correctly

A belt that slips, drags, or won’t move needs mechanical adjustment.

Check Belt Alignment: The belt should be centered on the deck. If it’s shifted to one side, use the hex wrench (usually provided) to adjust the rear roller bolts. Turn the left bolt a quarter-turn clockwise to move the belt right, and vice versa.
Adjust Belt Tension: If the belt slips under your feet, it’s to loose. If the motor strains or the belt won’t move, it’s to tight. Adjust both rear roller bolts equally, a quarter-turn at a time, until there’s about 2-3 inches of lift in the middle of the belt.
Lubricate the Deck: A dry deck creates friction. Unplug the treadmill, lift the belt, and apply silicone-based treadmill lubricant to the deck underneath. Spread it evenly by running the treadmill slowly for a minute.

Step-by-Step Repair Guides

Fixing a Noisy Weslo Treadmill

Squeaking, grinding, or thumping noises point to specific parts.

Squeaking: Usually means a dry deck or roller bearings. Lubricate the deck first. If noise persists, the roller bearings may need replacement.
Grinding: Often comes from the motor brushes wearing out or debris in the motor area. You’ll need to remove the motor hood to inspect.
This is almost always a loose or damaged belt. Check for tears or folds underneath and ensure proper tension.

Replacing a Worn Treadmill Belt

If your belt is cracked, frayed, or stretched out, it’s time for a new one.

Unplug the treadmill and loosen the rear roller bolts completely to slacken the old belt.
Slide the old belt off the front and rear rollers. You might need to tip the treadmill on its side.
Clean the deck and rollers thoroughly before installing the new belt.
Place the new belt over the rollers, center it, and then slowly tighten the rear roller bolts to achieve the correct tension.

When the Console is Blank or Malfunctioning

Console issues can be tricky, but start with the basics.

Loose Connections: The wire harness from the motor to the console can come loose. Check all plugs.
Faulty Incline or Speed Sensors: If speed or incline readings are wrong, the sensors near the motor or under the deck may need cleaning or replacement.
Console Board Failure: If all connections are good and power is reaching the console, the main board itself may be faulty and need to be swapped out.

Essential Maintenance to Prevent Problems

Regular care prevents most major repairs. A little upkeep goes a long way.

Clean Regularly: Wipe down the console, handrails, and belt after use. Vacuum underneath to prevent dust buildup in the motor.
Lubricate Every 3-6 Months: Follow your model’s manual for the proper schedule and use only silicone lubricant.
Check Tightness: Every few months, make sure all visible bolts and screws are snug, especially on the handrails and console.
Avoid Overloading: Stay within the user weight limit specified for your model to protect the motor and frame.

FAQ: Fixing Your Weslo Treadmill

Q: Where can I find the model number on my Weslo treadmill?
A: Look on the frame near the rear rollers or on the console’s base. It’s often on a white sticker. You’ll need this for ordering parts.

Q: My treadmill smells like its burning. What should I do?
A: Unplug it immediately! A burning smell usually indicates a overheating motor or a friction problem. Let it cool, check for obstructions, and inspect the belt tension and lubrication.

Q: Can I use WD-40 to lubricate my treadmill belt?
A: No, never use WD-40. It’s a degreaser, not a lubricant, and will damage the belt and deck. Always use a 100% silicone-based treadmill lubricant.

Q: How do I know if my motor is broken?
A: Signs include a complete failure to start (after checking power and safety key), a loud hum with no movement, or visible smoke/sparks. Testing with a multimeter is the definitive way to check.

Q: Are Weslo treadmill parts still available?
A: Yes, many common parts like belts, motors, and console boards are available from online fitness retailers. Knowing your exact model number is crucial for compatibility.
