Bad GAP HOME is a problem with the sensor (switch) that senses the automatically set printhead gap. Usually the wires break from flexing that run to the switch. Could be a bad switch also, or others.

You need to test the switch and wires with a meter.

Error 22-23-26


Precor Error Code 23
Error Code: 23 Manufacturer: Precor
Model: All Models
Error Description: Error 23, Motor Pulses Missing after Start Up - Indication that the speed sensor signal was lost while the unit was in operation. Possible Reason:
  1. The line of sight between the speed sensor and the speed sensor target is obstructed.
  2. Incorrect gap between the speed sensor and the speed sensor target.
  3. Incorrect adjustment of the speed sensor potentiometer (when equipped).
  4. Intermittent connection of speed sensor or drive motor wiring.
  5. Badly worn drive motor brushes not able to make proper contact with drive motor commutator.
  6. Faulty lower PCA.
  7. Faulty interconnect cable between upper and lower PCA.
  8. Faulty upper PCA.
Recommended Action:
  1. Using a static safe vacuum cleaner, carefully vacuum out the drive motor compartment. Be sure to thoroughly clean the area between the speed sensor and the speed sensor target.
  2. Inspect the gap of the speed sensor to the speed sensor target. Proper gap is 3/16" and the speed sensor photo eye should be aimed at the larger portion of the targets wedge shaped section. If unit has a magnetic speed sensor, the gap between the end of the sensor and the flywheel tooth needs to be 3/16".
  3. Locate the speed sensor potentiometer (when equipped) on the lower PCA. Set the speed sensor potentiometer to mid-range. Start the treadmill and increase speed to 6 mph. Carefully adjust the speed sensor potentiometer until the treadmill is operating the smoothest. Increase the speed to full speed and again adjust the speed sensor potentiometer until the treadmill is operating the smoothest. These two adjustments are typically small and are generally only a matter of fine tuning.
  4. Test all wiring and wire connections of the speed sensor and drive motor. Replace or repair necessary wire connections or wiring.
  5. Inspect and replace drive motor brushes if necessary.
  6. Determine if the lower PCA is bad by swapping with a known good lower PCA.
  7. Determine if the interconnect cable is bad by swapping with a know good cable.
  8. Determine if the upper PCA is bad by swapping with a know good upper PCA.
Precor Error Code 22
Error Code: 22 Manufacturer: Precor
Model: All Models
Error Description: Error 22, No Motor Pulses at Start Up - Error indicates that the display has sent a command for the drive motor to start, however, the speed sensor has not returned the signal acknowledging that the drive motor has started. Possible Reason:
  1. The line of sight between the speed sensor and the speed sensor target is obstructed.
  2. Badly worn drive motor brushes.
  3. Incorrect gap between the speed sensor and the speed sensor target.
  4. Incorrect adjustment of the speed sensor potentiometer (when equipped).
  5. Inoperative speed sensor.
  6. Faulty lower PCA.
  7. Faulty interconnect cable between upper and lower PCA.
  8. Faulty upper PCA.
Recommended Action:
  1. Using a static safe vacuum cleaner, carefully vacuum out the drive motor compartment. Be sure to thoroughly clean the area between the speed sensor and the speed sensor target.
  2. Bady worn drive motor brushes cannot make proper contact with the motor commutator, therefore the drive motor will not start when voltage is applied. Inspect and replace drive motor brushes if necessary.
  3. Inspect the gap of the speed sensor to the speed sensor target. Proper gap is 3/16" and the speed sensor photo eye should be aimed at the larger portion of the targets wedge shaped section. If unit has a magnetic speed sensor, the gap between the end of the sensor and the flywheel tooth needs to be 3/16".
  4. Locate the speed sensor potentiometer (when equipped) on the lower PCA. Set the speed sensor potentiometer to mid-range. Start the treadmill and increase speed to 6 mph. Carefully adjust the speed sensor potentiometer until the treadmill is operating the smoothest. Increase the speed to full speed and again adjust the speed sensor potentiometer until the treadmill is operating the smoothest. These two adjustments are typically small and are generally only a matter of fine tuning.
  5. An inoperative speed sensor will allow the drive motor to start and run briefly before the error appears. If able to access the speed sensor wiring, measure the DC voltage between the speed sensor leads. Two of the leads will always read about 5 VDC. Two will toggle between 0 and 5 VDC as you slowly turn the speed sensor target. If both measurements are not seen, the speed sensor needs replaced. Some units have the speed sensor mounted on the lower PCA and the lower PCA needs replaced.
  6. Determine if the lower PCA is bad by swapping with a known good lower PCA.
  7. Determine if the interconnect cable is bad by swapping with a know good cable.
  8. Determine if the upper PCA is bad by swapping with a know good upper PCA.

Precor Error Code 26 Error Code: 26 Manufacturer: Precor
Model: All Models
Error Description: Error 26, Motor Pulse Width Incorrect - Observation of the speed sensor signal and verification the signal from the speed sensor is appropriate for the requested speed. If an incorrect or erratic speed sensor signal is detected the error appears. Possible Reason:
  1. The line of sight between the speed sensor and the speed sensor target is obstructed.
  2. Incorrect gap between the speed sensor and the speed sensor target.
  3. Incorrect adjustment of the speed sensor potentiometer (when equipped).
  4. Damaged speed sensor target.
Recommended Action:
  1. Using a static safe vacuum cleaner, carefully vacuum out the drive motor compartment. Be sure to thoroughly clean the area between the speed sensor and the speed sensor target.
  2. Inspect the gap of the speed sensor to the speed sensor target. Proper gap is 3/16" and the speed sensor photo eye should be aimed at the larger portion of the targets wedge shaped section.

These two adjustments are typically small and are generally only a matter of fine tuning.
  4. Inspect the speed sensor target for any scratches or tears that could cause incorrect readings. Replace the speed sensor target if necessary.

Precor error codes 53


Precor Error 53, Can't Read Target, Can't Find Home Switch Probable Cause 1. Blown F2 fuse.
2. Home switch wiring is damaged or has intermittent connection.
3. Gear (elevation/incline) motor wiring is damaged or has intermittent connection.
4. Home switch is bad.
5. Gear (elevation/incline) motor is bad.
6. Gear (elevation/incline) motor target is damaged.
7. Lower PCA is bad.
Corrective Action
  1. Disconnect power from the unit. Remove the F2 fuse from the lower PCA. Using an ohm meter, measure the fuse for 1 ohm or less. If the reading is considerably high, replace the fuse. If the fuse is blown, inspect further for the cause to avoid the fuse blowing again. Inspect for damaged gear motor wiring or a bad gear (elevation/incline) motor. Replace if necessary.
  2. Thoroughly inspect the home switch wiring for damage or intermittent connections. Repair or replace damaged wiring or poor connections as necessary.
  3. Thoroughly inspect the gear (elevation/incline) motor wiring for damage or intermittent connections. Repair or replace damaged wiring or poor connections as necessary.
  4. Ensure the moving arm is away from the home switch and disconnect power from the unit. Disconnect both wires from the home switch. Using an ohm meter, check for approximately 0 ohms. Continue to monitor the home switch resistance and activate the home switch by hand. The reading should change from approximately 0 ohms to open (infinite). If either reading is considerably incorrect, replace the home switch.
  5. With unit disconnected from power, disconnect both wires from the gear (elevation/incline) motor. Using an ohm meter, check for approximately 9 ohms through the gear (elevation/incline) motor wiring. If the reading is considerably high or low, replace the gear motor.
  6. Inspect the gear (elevation/incline) motor target for rips, tears, or bad scratches. If any of these are found, replace the target.
  7. During the start up sequence, check the voltage at the gear (elevation/incline) motor. Voltage should be approximately 12VDC. The voltage should only be present between the time the sequence was started and the error 53 occurred. If the voltage is considerably low or absent and the F2 fuse proved good, replace the lower PCA.

Craftsman 32cc weed trimmer will not stay running when trigger depressed after start & warmup ... Bad gas? Plug gap? Choke adjustment? Suggestions?


Check the fuel filter, air cleaner, and muffler for plugging. Check the fuel lines for decay or other damage. Plug gap should be 0.020". Bad fuel usually means poor starting and idling as well as poor high speed running. Try setting the H jet needle CCW somewhat to increase fuel input to the engine. It should 4-stroke lightly at speed, then 2-stroke immediately when the line is cutting. Be sure to use a modern synthetic saw oil in the fuel (available at home centers, hardware stores, and saw dealers) and be sure to shake the container thoroughly just before filling the tank each time to prevent oil starvation. Hope this helps!

Won't spin, error LE appears on display


If the washer seems to complete all of its cycles, but doesn't spin: 1) Be sure the load of clothes is not lop-sided. If the tub becomes unbalanced, it may spin erratically or not at all. Open the lid after 2 minute gap and reposition the clothes. This automatically resets an off-balance shut-off switch. Close the lid and re-try. 2) Check the lid switch and the tab on the lid that strikes it. If the plastic tab is broken, the washer may halt during the spin cycle. If the switch doesn't click when you press and release it, it's probably broken. If you're experienced at home repair, you can remove the switch, test it, and replace it if needed; otherwise, call an appliance repair service person. 3) The belt may be loose, worn, or broken. If you're fairly handy, tighten or replace the belt, otherwise call an appliance repairperson. Pl post back results
