SOURCE: stairmaster gravitron compressor does not empty

Unplug the solenoid valve from the bottom of the power supply and plug it directly into a wall outlet. That should actuate the valve to release the air. If that doesn't work you will need to replace the valve. Good luck.

Stairmaster config rqrd


Display reads CONFIG RQRD or NTM CONFIG RQD on Stairmaster Equipment Probable Cause The message CONFIG RQRD or NTM CONFIG RQD appears when the console needs to be configured for the machine type it is installed. This message is common when the console has been replaced or if the settings have been changed. Message is commonly seen on various Stairmaster equipment such as bike models 3000CE, 3300CE, 3400CE, 3600RC, 3800RC and 3900RC; stepper models 4400PT, 4600PT, 4400CL, 4600CL and SC916; stepmill models 7000PT and SM916; elliptical model ClubStride 5100.
Corrective Action
  • Make sure the unit is in an "idle" state. "Idle" state means the console is not displaying an error or any message that requires data input. The display should basically be freshly powered up, scrolling the EKG or welcome message
  • Configure the console for the proper machine type by pressing Level UP, 80, ENTER
  • Using the Level UP or Level DOWN keys, scroll through to the proper machine type (Bike, Elliptical, Stairclimber or Stepmill)
  • Once the proper machine type is shown on the display select the machine type by pressing ENTER
  • This completes the steps necessary when your Stairmaster display reads CONFIG RQRD or NTM CONFIG RQD

Alternator Belt Replacement for Stairmaster 4000PT Stepper


Stairmaster Stepper 4000PT Alternator Belt Replacement WARNING: The belts must be properly tensioned. A belt that is too loose will cause slow and sluggish operation. A belt that is too tight will cause excessive noise and belt wear.
  1. Remove side covers.
  2. Loosen the adjustment screw that mounts the alternator to the alternator brace and the pivot adjusting bolt that mounts the alternator to the frame.
  3. Pivot the alternator down and remove the belt.
  4. Make sure the is centered on the pulleys during installation.
  5. Pivot the alternator up or down as necessary to allow 1/4" (0.6 cm) of belt deflection with fingertop pressure at the midpoint between the two pulleys.
  6. Tighten the alternator adjustment bolt. Verify 1/4" (0.6) deflection in the belt.
  7. Reinstall the covers

I have a 440pt and the left pedal is skipping down to the floor about every 5 seconds. If the issue is the hub assemble, do I have to change out everything or can I just replace the bearing, etc...?


Why does one pedal drop on my Stairmaster Stepper but the other pedal operates correctly? Stairmaster Steppers, How to Troubleshoot when one Pedal Drops (Loses Resistance) while the Other Pedal Operates Correctly
  • If one pedal drops while the other operates correctly on your Stairmaster stepper, this problem commonly occurs when the drive sprocket on one side or the other becomes defective
  • Usually, when one drive sprocket fails, the other isn't too far behind
  • The best approach to resolve this problem is to install a new hub assembly

Compressor reaches upper pressure limit of 120 psi but does not shut down or increase in pressure. When manually shut off at near 120 psi it will hold pressure for extended time.


Hi

Here are a few things to check, you may have already checked some of these.

Electricity...Compressors will run best with full 115Vot 15AMP/Or 220V electrical supply from a circuit, over the shortest electrical cord as possible.

Air Leaks..Place your ear close to the compressor and listen for air leaking, if you hear air that is not normal and means you have to locate and repair whatever it is that is leaking.
Check the air unloader valve... The air unloader valve will blown out air when you turned off the compressor, that is normal.
But it should not have air leaking out of it all of the time. If so then it is faulty and in need of repair/replacement.

Valves...If either the intake or exaust valves fail, breaks, or fails to seat, then your compressor will run 24 hours a day and never build up to the correct pressure for shut-off.

Gaskets...Check to see if your gaskets have failed.
You could have a gasket failure between the pistons and you will never know it because it shows no external air leak.
If this situation happens then the air will only cycle between cylinders and never build up the correct air pressure.
One way to check the gasket is remove the air filter, then put your hand over the intake.
If correct then it will **** you hand against the intake.
If the valve or valves have failed then you will feel the air sucking in and blowing out.

Piston Rings and Cylinder...The piston rings could be stuck,broken, or worn and not allowing the correct pressure to build up in your tank.
It will contribute to not shutting off the compressor motor thru the use of the pressure switch.
A worn cylinder will also contribute to the problem of pressure build-up.

Pressure Switch...Check for air leaks at the pressure switch, it has a rubber diaphram that can fail and leak air out of the system.
Please take time to rate me
