Introduction: When Part of Your Cryolipolysis Machine Stops Working
In daily operation, many clinics encounter a frustrating issue: the cryolipolysis machine powers on, the cryo handle works normally, but other handles such as cavitation or RF stop working.
This kind of fault is common in multi-function fat freezing devices, especially when used frequently.
In this real after-sales case, we analyzed a FR-CY24 cryolipolysis slimming machine, identified the root cause, and restored the system to normal operation.
If your cryo body sculpting machine is partially not working, this guide will help you diagnose it step by step.

1. Problem Description: Only Cryo Handle Works, Other Handles Fail
Real Case
A clinic reported:
- Cryolipolysis handles cooling normally
- Cavitation / RF handles not responding
- Screen working correctly
This means the main system is partially functional, but some modules are not receiving power.2. Root Cause Analysis (Most Important Part)
Based on our inspection, this issue is usually NOT a major hardware failure.
Common Causes:
① Loose Internal Wiring
The connection between:
- Main board
- Function control board
may become loose during transportation or long-term use.
② Function Board Failure
If wiring is normal, the problem may come from:
- Damaged function board
- Power not reaching sub-board
Especially check AC220V power line connection

3. Step-by-Step Repair Solution
Step 1: Disassemble the Machine
- Remove rear screws
- Open back cover
- Locate upper and lower boards
Step 2: Check Power Wiring
Focus on:
- AC220V cable
- Wiring between boards
Follow the cable path and check for looseness
Reconnect if necessary
If wiring is normal → move to next step
Step 3: Determine Function Board Status
If:
√ All cables are properly connected
√ Cryo handle works
× Other handles not working
Then the issue is likely function board damage
4. Additional Common Problems & Solutions
Problem A: Machine Not Filled with Water
Symptom
- Cryo handle overheating
- No cooling effect
Solution
- Fill tank with distilled water
- Start machine
- Let cooling begin
- Refill water again
Shipping removes water to avoid leakage, so this step is critical
Problem B: Cryo Handle Not Cooling or No Suction
Diagnosis Flow:
- Check water level
- Check connector lock
- Test different ports
If Handle Not Cooling
99% → insufficient water inside handle
Solution → shake handle to push water inside
If Still Not Cooling
Cooling plate may be damaged → replace
Problem C: No Suction
Possible Causes:
- Blocked handle
- Filter leakage
- Air pump damage
Solution:
Clean handle (water or air pump)
Check filter connection
Inspect air pump
Problem D: Frostbite During Treatment

Cause:
- Insufficient antifreeze membrane
- No pre-heating
- Incorrect operation
Solution:
Use 2–3 layers antifreeze membrane
Perform RF heating before cryo
Apply post-treatment care
Especially important for sensitive skin users
Problem E: Clicking Sound During Vacuum Mode
Explanation:
This is the normal operation sound of the solenoid valve
No repair needed
No risk
5. How to Avoid These Problems in Daily Use
To maintain a stable cryolipolysis slimming machine, clinics should:
- Always fill water before use
- Check connectors before treatment
- Perform regular maintenance
- Train operators properly
6. Why After-Sales Support Is Critical for Clinics
From our experience, most issues are not caused by machine failure, but by:
- Incorrect operation
- Lack of technical guidance
- No supplier support
Choosing a supplier with strong after-sales service can:
Reduce downtime
Protect clinic reputation
Improve treatment efficiency
7. Upgrade to a More Stable Fat Freezing Device
If your current machine frequently encounters issues, upgrading to a professional cryo body sculpting machine can:
- Reduce maintenance frequency
- Improve treatment consistency
- Increase customer satisfaction
