What to Do If Your Freeze Dryer Touchscreen Isn’t Responding

If your freeze dryer’s touchscreen isn’t responding to your touch, or if it seems “off” (for example, you tap one spot but something else is selected), don’t worry—there are steps you can take to fix it. This guide will help you figure out what to do, based on your machine’s software version.

Common Signs of Touchscreen Problems

The touchscreen doesn’t respond at all when you touch it
Touches are detected in the wrong place on the screen
The screen looks normal, but touch is inaccurate or “off”
You can’t move through menus or change settings because the screen won’t respond
The touch calibration seems wrong or drifts over time

Step 1: Find Out Your Touchscreen Type

The right solution depends on your software version, which tells you what kind of touchscreen you have:

Resistive Touchscreen: Software versions starting with 2, 3, 4, 5.0, or 5.2
Capacitive Touchscreen: Software versions starting with 5.1, 5.4, 5.5, or 6

Important: Capacitive touchscreens cannot be recalibrated. If you have a capacitive screen, recalibration is not possible—software updates are the correct solution.

If you’re not sure which version you have, check your freeze dryer’s home screen or settings menu for the software version number.

Step 2: Try These Quick Fixes

Check your software version to identify your touchscreen type
For resistive screens: Try recalibrating the screen (see below)
For capacitive screens: Look for available software updates (recalibration is not possible)

Step 3: Troubleshooting Steps

For Resistive Touchscreens (Software versions 2, 3, 4, 5.0, 5.2)

How to Recalibrate the Screen:

Turn off your freeze dryer.
Turn it back on. As soon as the screen lights up, press and hold anywhere on the screen.
Keep holding until you hear a beep or buzzing sound, then lift your finger.
Follow the on-screen instructions to tap the 3 blinking circles.
Wait for the machine to finish starting up.
Test the screen by moving through menus and changing settings.

For Capacitive Touchscreens (Software versions 5.1, 5.4, 5.5, 6)

How to Update the Software:

Capacitive touchscreens cannot be recalibrated—software updates are the solution.
For versions starting with 5.1: Get the latest software here
For versions 5.4, 5.5, or 6: Get the latest software here
Follow the instructions on the update page.
Test the touchscreen after updating.

Important Reminders

Your software version determines your touchscreen type and the right troubleshooting steps.
Capacitive touchscreens cannot be recalibrated—only software updates can fix touch issues.
Resistive screens need physical recalibration.
Complete the full calibration process for resistive screens without stopping.
Always follow official software update instructions.
Test your screen thoroughly after any fix.
