LCD Thermostat Temperature Sensor (old) – The sensor that detects the incubator's internal temperature and allows the LCD thermostat to regulate the heating. This critical component constantly transmits temperature data to the thermostat to maintain the incubator at 37.5-37.7°C.

When is it needed? If the LCD control unit displays an incorrect or fixed temperature , or the internal temperature fluctuates too much . Even if you see "Err" or "---" on the display, or if the heating element remains always on or always off, ignoring the actual temperature.

Symptoms of a faulty probe: Displayed temperature stuck on one value, impossible readings, resistor that never turns on or off, sudden temperature fluctuations.

💰 Price: €13.70 each (excluding VAT, excluding transport) – FIEM WAREHOUSE COMO – Only original FIEM components from Padovan Avicoltura for guaranteed efficiency over time.

⚠️ OLD Version: This probe is for older models with LCD control units. Newer models with MiniLED Advanced or other modern control units use different probes (T/H PROBE).

Compatibility: MG Series (older LCD models) and CIP CIP (older LCD models). Please check that your incubator has the old LCD control unit before ordering.

Minimum order €20: Consider ordering at least 14 probes (€20.58) as a backup for future replacements, or supplement with other spares (fuse, thermometer, trays).

📦 Logistics: Dispatch within 1 business day, delivery within 2-4 days. Warranty: 24 months for private individuals / 12 months for VAT number. FIEM since 1975.

🔍 When is this probe needed?

The temperature probe must be replaced when:

  • Incorrect temperature displayed: The LCD display shows clearly incorrect values
  • Reading locked: The temperature remains fixed at one value (e.g. always 25°C)
  • Error on display: "Err", "---" or other error codes appear
  • Excessive fluctuations: Temperature fluctuates by ±2-3°C instead of remaining stable
  • Resistance always on: It never turns off, temperature rises above 40°C
  • Resistance always off: It never turns on, temperature drops below 35°C
  • Impossible values: Display shows -10°C, 60°C or other unrealistic values
  • Physically damaged probe: Cable cut, crushed or burned

⚠️ What is the probe and why is it essential?

The temperature probe is the critical sensor of the control system:

  • Detect internal temperature: Constantly measures the temperature in the incubator
  • Transmits data to the control unit: Sends the electrical signal to the LCD control unit
  • Allows automatic regulation: The control unit turns the resistance on/off based on the probe data
  • Vital precision: Variations of 1°C can compromise hatching
  • Without a working probe: No automatic temperature control → lost eggs

⚠️ Before ordering: diagnostics

Is the probe really the problem?

Rapid tests:

  1. Compare display temperature to analog thermometer: Place a control thermometer in the incubator and compare it with the LCD display. A difference of >2°C means the probe is likely faulty.
  2. Observe the behavior: Does the displayed temperature change when you open/close the incubator? If it stays the same, the probe is blocked.
  3. Visual cable inspection: Verify that the probe cable is not cut, crushed or burned.
  4. Check connection: Check that the probe is properly connected to the LCD control unit (it may have become disconnected).

If the problem persists even after replacing the probe: The LCD control unit itself could be faulty.

📸 In doubt? Send us photos on WhatsApp of the LCD display showing the abnormal temperature and the probe: we'll help you diagnose.

Sensor type Temperature probe (type to check: NTC/PTC)
Function Internal incubator temperature detection
Compatibility LCD control unit (old) MG and CIP CIP series
Connection Cable with connector for LCD control unit

🔧 Replacement

Procedure (accessible even to non-expert users):

  1. Unplug the incubator from the socket
  2. Open the incubator
  3. Locate the temperature probe (cable that starts from the LCD control unit and enters the incubator)
  4. Disconnect the old probe's connector from the LCD control unit
  5. Gently remove the probe from inside the incubator
  6. Insert the new LCD T.PROBE probe into the same spot
  7. Connect the connector to the LCD control unit
  8. Reconnect the plug and check that the display shows the correct temperature
  9. Wait 10-15 minutes for stabilization and compare with analog thermometer

💡 Advice from 45 years of experience: After replacing the probe, let the temperature stabilize for at least 30 minutes before loading the eggs. Check with an analog thermometer that the temperature is actually correct.

❌ Common mistakes to avoid

  • Do not place the probe in its original place, for example near the resistor: it would read too high a temperature.
  • Do not place near the fan: It would read a lower temperature than the actual one
  • Do not pinch the cable in the lock: You risk damaging the new probe
  • Do not pull the cable forcefully: Gently pull out the old probe

❓ Frequently Asked Questions (FAQ)

Q: Will this probe fit my new MG50?
A: It depends. If you have the old LCD control unit, yes; if you have the MiniLED Advanced, no (you need a T/H probe). Send a photo of the control unit on WhatsApp for verification.

Q: Can I use a generic probe instead of the original FIEM one?
A: Not recommended. Probes have specific electrical characteristics, and a generic one could give incorrect readings.

Q: How long does a temperature probe last?
A: With proper use, 5-10 years. It depends on annual incubation cycles and environmental conditions.

Q: If the probe malfunctions, can I continue incubating?
A: Very risky. Without precise temperature control, the eggs can die or become damaged. It's best to replace them before starting new cycles.

Q: How do I know if I have an old LCD control unit?
A: If the display is an LCD with black digits on a gray/green background (no bright LEDs), it's the older version. Send us a photo on WhatsApp if you have any questions.

Solution: Original FIEM GACOS for COSMO, COSMO EVO, and COSMO ML incubators. Price each.

📌 Real case: A customer in Treviso with a COSMO EVO had a car that wouldn't close properly and was losing heat. He thought it was an electrical problem, but it was just a broken GACOS. It was replaced in 2 minutes, and the problem was solved for less than 3 euros.

⚠️ When to replace: If the two shells no longer fit securely or you notice any play between the parts, check the GACOS immediately. An imperfect seal disperses heat and moisture.

Perforated Bottom Grid for Fiem Smart / Plasti Flor

Perforated Bottom Grid for Fiem Smart / Plasti...

€11.80
Availability: 999 In Stock

🥚 The Smart net is not a simple shelf: it is the perforated technical floor that supports the eggs allowing perfect circulation of air and humidity from below!

At €9.70 (excluding VAT) , the SMART PL. NET (component no. 11 in the exploded view) is the support grid where you place your eggs. Its perforated structure is not random: it allows warm air to circulate evenly from bottom to top and the humidity from the four sectors below to evaporate, reaching the eggs, creating the perfect microclimate essential for embryonic development.

💨 As the FIEM manual specifies, air circulation is as crucial as temperature. Hot air rises through the mesh, enveloping each egg evenly, while the moisture evaporating from the trays at the base passes through the grill, maintaining the proper 47-62% ratio needed for the various stages.

⚠️ When should you replace it? If the mesh is broken or warped, compromising the egg holder, if the plastic is bent, creating unevenness, if it's clogged with debris blocking airflow, or after several cycles, when thorough cleaning is required.

💡 The mesh size is designed to hold eggs of various sizes (from quail to goose), always ensuring optimal airflow and humidity. Without this perforated grid, you wouldn't have the necessary ventilation!

✅ Compatible exclusively with the Smart model . Specific dimensions and design to fit perfectly into the structure.

🎛️ The front panel is not just an aesthetic mask: it is the access panel to the electronic heart of your Smart, protecting the vital controls!

At just €7.50 (excluding VAT) , the F/SMART front panel (part no. 7 in the exploded view) is the front cover that protects the incubator's controls and makes them accessible. It's more than just decorative plastic: it keeps the switches and display protected from the constant humidity of the incubation environment.

⚡ This seemingly simple component performs critical functions: it protects electrical components from moisture and dust, maintains access to controls, prevents accidental contact with electrical parts, and ensures the professional appearance of your incubator.

🔧 When should you replace it? If it's cracked or broken, if it no longer attaches properly to the frame, if the plastic is discolored or warped from heat, if the switch or display holes are damaged, or after maintenance that has compromised it.

💡 The faceplate covers the area where the thermostat, switches, and electrical connections are located. Inadequate protection in this area can cause malfunctions due to moisture penetrating the circuitry.
