Our Force Trainer, which has new batteries, will not calibrate. Although the tower and the headset both turn on, (the tower first as instructed), the fan does not come on and the blinking lights on the tower never stop blinking.

Hi,
Try to do the following hope it will solve the problem.
if its doesn't solve the problem then the the incline motor or the control panel is faulty.
HOW TO USE THE SETTINGS MODE T
he console features a settings mode that allows you to connect your incline trainer to your own wireless network and to log in to your iFit Live account. The settings mode also allows you to turn on and turn off the display demo mode. You may also be able to select the unit of measurement.
Select the settings mode.
Insert the key into the console . Next, select the start menu. Then, press the i button in the lower right corner of the screen to select the settings mode.
Select the maintenance mode.
Press the Maintenance button in the lower right corner of the screen to enter the maintenance mode.
Calibrate the incline system of the incline trainer.
Press the Calibrate Incline button. The incline trainer will automatically rise to the maximum incline level, lower to the minimum incline level and then return to the starting position. This will recalibrate the incline system. Press the Begin button to calibrate the incline system or the Cancel button to return to the maintenance mode. When the incline system is calibrated, press the Back button. IMPORTANT: Keep pets, feet, and other objects away from the incline trainer while the incline is calibrating. In an emergency, pull the key from the console to stop the incline calibration.
Restore factory defaults.
If necessary, press the Restore Defaults button to reset the firmware to the original factory firmware. This will erase all firmware updates that you have downloaded. Press the Begin button to restore the default firmware or the Cancel button to return to the maintenance mode. When the restoration is complete, the words PLEASE CYCLE POWER will appear in the grey box. Press the power switch into the off position. Wait for several seconds, and then press the power switch into the reset position. It may take a minute for the console to be ready for use.
Exit the maintenance mode.
To exit the maintenance mode, press the Back button repeatedly.

I am assuming this is not a sound issue, and an entire headset not coming on issue. Here are the steps that I would take...
1. Put in BRAND NEW BATTERIES!!! (Usually that is the culprit) ;-)
2. Unplug and then re-plug in all wires and cords to the console and the controller.
3. Check to see if the wires are connected from headset to end cords (on the one that plugs into the controller).
4. Once everything is connected and with brand new batteries, it should work, turn it on again. Remember the beep sound goes up when the turtle beaches come on, and the beep sound goes down when the turtle beaches are turned off.

RUN the software calibration for easy diagnostic and fix it. Read you owner manual and follow the steps.
God bless you

please RUN the software calibration for easy diagnostic and fix it.
Go under the HOOD cover for motor, and see the instruction and follow the instruction
God bless you

The batteries are probably low, first the headset will give out one beep per minute, which rises to almost every second. I had a problem with this too.

Please test the REED switch, for open or fault. Clean it, and tight the connector very well. See the diagram attached.
2) Tight the ribbon cables, clean it for keypads.
3) Replace old batteries by new ones, clean the contacts batteries very well. and try again. see the block diagram
4)Run the software calibration for troubleshooting,
God bless you

Batteries are probably dead, order a new set or try using disposable ones

Time for new ones, or try and claim on the warranty.

My name is Mike; I am a service technician for ICON Health & Fitness, the manufacture of the machine mentioned. While my comments on your problem are geared generally to assist, you are welcome to call our customer service line at 18009993756 for specific instructions if needed.
The first thing to do with any incline problems with a treadmill is run “calibration.” Calibration restores all settings (including the incline sensor in this case) to the factory specs. Instructions to run calibration on your individual machine are taped on the underside of the motor hood. See your manual for removal of the hood. While each machine has specific calibration instructions most new models made by ICON will have similar steps to doing it.
To calibrate the incline you will need to press and hold the Stop and Speed + buttons while inserting the safety key or magnet. Then let go of the buttons. This will enter calibration level 1 which lists some machine information and a console memory test. Press the Stop button 1 time. This will enter level 2 of calibration. To calibrate the incline you can press either incline buttons (either the up or down arrows) and your incline should go all the way up and then all the way down. If this works then take the safety key or magnet out; turn the power off, and unplug it for several minutes. (On a side not you will want to turn the power off and unplug your machine whenever you’re not using it.)
If this does not fix the problem then it can be more complicated depending on the model and motor involved. It can range from the console not sending a signal to a loose wire or jammed motor. If this didn’t fix the problem then I would recommend calling in for further assistance.
Sincerely,
Mike
