You may notice the door stopping halfway, hearing a strained grinding noise, or the unit failing to respond to remote commands entirely. While this error indicates a serious mechanical or electronic obstruction, it is entirely fixable with a methodical, safety-first approach. Do not attempt to force the door, as this can lead to cable snapping or motor failure; follow this guide to restore functionality safely.
Symptoms of Excessive Travel Time Error
As a Safety Compliance Officer, I must emphasize that recognizing these symptoms early is vital to preventing property damage or personal injury. The primary indicator is the diagnostic display on the motor head, which will flash the “Up” arrow four times followed by the “Down” arrow five times. This is the system’s way of “locking out” to prevent further damage.
🛑 Safety Precaution: High Voltage
Incorrect repairs can cause fire or injury. Always verify with the manufacturer’s manual.
Physically, you may observe the door moving at a significantly reduced speed before it abruptly halts. You might hear a clicking sound from the logic board as it cuts power to the motor. In many cases, the motor will hum loudly but fail to move the trolley, suggesting that the drive system is slipping or the door is stuck in the tracks. Unlike a simple sensor misalignment, this error usually involves the physical movement of the door failing to meet the timing parameters programmed into the logic board.
Comprehensive Repair Guide
WARNING: Before beginning any inspection, you must disconnect the power cord from the electrical outlet. Working on a garage door opener while it is energized poses a severe risk of electric shock or accidental entrapment. Ensure the door is fully closed or securely propped before releasing the emergency cord.
- Perform a Manual Balance Test:
Pull the red emergency release cord to disconnect the opener from the door. Manually lift the door halfway. Safety Check: If the door does not stay in place or falls rapidly, your springs are broken or improperly tensioned. Stop immediately and call a professional. If the door moves smoothly, the issue is likely within the opener unit itself. - Inspect the Internal Drive Gear:
Using your Phillips head screwdriver, remove the outer cover of the motor housing. Inspect the white plastic gear located near the motor shaft. Look for “plastic snow” (shavings) inside the case. If the teeth are flattened, you must replace the gear and sprocket assembly. Use a multimeter to check for continuity across the motor windings if you suspect an electrical short. - Clean and Align the Tracks:
Use a damp cloth to remove grease and debris from the internal “V” of the tracks. Do not use heavy grease; instead, apply a specialist silicone-based garage door lubricant to the rollers and hinges. Obstructions as small as a pebble can cause the travel time to exceed the 30-second safety limit. - Reset the Travel Limits:
If no mechanical faults are found, the logic board may have lost its positioning. Locate the “Adjustment” button (usually black) between the Up and Down arrows. Press and hold the adjustment button until the Up arrow flashes. Use the arrows to set the open and closed positions. Mandatory Safety Test: After resetting, you MUST perform a safety reversal test by placing a 2×4 piece of wood under the door to ensure it reverses upon contact. - Verify RPM Sensor Connection:
The RPM sensor is a small circuit board located at the end of the motor shaft. Ensure the wiring harness is seated tightly. If the sensor is dusty, clean it with compressed air. If the sensor is faulty, the motor will move for about 2 seconds and then stop, triggering the 4-5 error code.

Detailed Diagnosis: Root Causes
The “Excessive Travel Time” error is rarely a random glitch; it is a calculated response by the opener’s firmware to one of the following mechanical or electronic failures:
- Mechanical Binding or Obstruction: Over time, garage door tracks can become misaligned, or rollers can seize due to lack of lubrication. If the door encounters friction that requires more torque than the “Force” settings allow, the motor slows down. If it takes longer than 30 seconds to travel the length of the track, the logic board triggers Error 4-5.
- Broken Torsion or Extension Springs: This is a high-hazard condition. Springs are responsible for counterbalancing the door’s weight. When a spring snaps, the door becomes “dead weight,” often exceeding 150-300 lbs. The motor is not designed to lift this much weight alone. It will struggle, slow down, and eventually time out to prevent the motor from melting down.
- Worn Drive Gear and Sprocket Assembly: In many Craftsman chain or belt-drive models, the internal drive gear is made of high-strength plastic. Over years of use, the teeth can strip. If the motor is spinning but the gear is slipping, the door travels slower than expected or not at all, leading to a travel time violation.
- Voltage Spikes or Logic Board Failure: A power surge can damage the RPM sensor or the travel limit module on the logic board. If the board cannot “count” the rotations of the motor, it assumes the door is not moving and shuts down the system as a safety precaution.
How to Prevent Error 4 Up 5 Down
To ensure your garage door system remains compliant with safety standards and avoids the “Excessive Travel Time” fault, follow these preventative measures:
1. Bi-Annual Lubrication and Inspection:
The most common cause of travel errors is friction. Every six months, apply a high-quality lithium or silicone spray to all moving parts, including rollers, hinges, and the torsion spring. Avoid using WD-40, as it is a degreaser, not a long-term lubricant, and can actually increase wear over time.
2. Install a Dedicated Surge Protector:
The logic boards in Craftsman openers are highly sensitive to voltage fluctuations. By plugging your opener into a single-outlet surge protector, you shield the sensitive RPM sensors and travel limit chips from “ghost” errors caused by electrical interference or lightning strikes.
3. Annual Balance Verification:
Once a year, pull the emergency release and check the door balance yourself. A well-balanced door should be easy to lift with one hand. If the door feels heavy, the motor is working overtime, which will inevitably lead to a travel time error and premature motor failure.
Frequently Asked Questions
Q: Can I just increase the “Force” settings to bypass this error?
A: Strictly speaking, NO. Increasing the force settings to overcome a mechanical binding issue is a significant safety violation. It can lead to the door failing to reverse when it hits an object (or a person), resulting in catastrophic injury. Always fix the underlying friction or balance issue instead of “masking” it with more motor force.
Q: Why does this error happen more frequently in the winter?
A: Cold temperatures cause metal tracks to contract and grease to thicken. This increase in physical resistance often pushes a borderline-functioning opener past the 30-second travel threshold. Ensuring you use “all-weather” silicone lubricant can mitigate this seasonal issue.
Q: My motor makes a humming sound for 30 seconds but the chain doesn’t move. Is this Error 4-5?
A: Yes. This usually indicates that the drive gear has completely stripped or the carriage is jammed against a stop bolt. The motor is “traveling” in its own mind, but since the door isn’t moving, it eventually hits the 30-second timeout. Disconnect power immediately to prevent the motor from burning out.
