🔍 When to Replace the Resistor – Typical Symptoms
The silicone resistor should be replaced when one or more of the following symptoms occur:
- Temperature not reached: The incubator never reaches the set temperature (e.g. 37.7°C) even though the thermostat is always on.
- Very slow warm-up: It takes hours to reach working temperature (usually 15-30 minutes is enough)
- Thermostat always on: The thermostat LED always stays on but the temperature doesn't rise
- Abnormal temperature fluctuations: The temperature varies continuously by several degrees without stabilizing
- Fuse blowing repeatedly: It could indicate a short circuit in the resistor
- Visible signs of damage: Cable cut, burnt, blackened or with damaged silicone sheath
- Burning smell: Coming from the heating area (turn off the incubator immediately)
⚠️ Before ordering: quick checks to do
Are you sure it's the resistor? Before proceeding with your purchase, please perform these checks:
- Always unplug the power cord from the power outlet (safety first)
- Check the fuse: Check that the 2A fuse is intact (if it is blown, replace it first and try again)
- Check the thermostat: Check that the thermostat is set correctly and is working (LED turns on/off)
- Visual inspection of the resistance: Remove the panel and visually inspect the cable: are there any cuts, burns, or blackened spots?
- Test with tester (multimeter): Disconnect the resistor from the electrical connections and measure the resistance with a tester in Ohm mode. You should read about 505 Ohm (2.06 mt × 245 Ohm/mt = 504.7 Ohm). If you read "infinity" (∞) or "OL" → the resistor is open. If you read 0 Ohm → there is a short circuit.
- Check connections: Check that the electrical connectors are well inserted and not oxidized

ATTENTION SAFETY
Electrical Intervention – Maximum Caution Required
- ALWAYS unplug the power cord from the power outlet before any operation
- Never intervene with the incubator switched on or connected to the mains.
- No part must be under tension during work
- If you are not familiar with electrical connections → rely on a qualified electrician
- The resistor operates at 230V: an error can be dangerous
Replacement procedure (for experienced people only):
- Unplug the power cord from the electrical outlet
- Remove the upper control panel
- Photograph the electrical connections before disconnecting any cables (you will need them for reassembly)
- Disconnect the electrical connectors of the old resistor (usually fastons or terminals)
- Remove the retaining collars holding the heating cable in place
- Gently slide the old resistor out following the original path
- Place the new R75E resistor following exactly the same path as the old one
- Secure the cable with the support collars (avoid sharp bends or excessive tension)
- Connect the electrical terminals respecting the polarity (see the photo taken previously)
- Make sure the cable does not touch any metal or sharp parts
- Reassemble the control panel
- Reconnect the plug and turn on the incubator
- Monitor carefully warm up for the first 30 minutes to check that it is working correctly
💡 Advice from 45 years of experience: When replacing the heating element, also replace the fastening collars if worn and thoroughly clean the inside of the incubator. Always check the condition of the fuse.
❌ Common mistakes to avoid
- Don't bend the cable too tightly: Too small bending radii can damage the internal heating wire
- Do not pull or over-tighten the cable: It must be laid without mechanical tension
- Do not reverse the connections: Follow the original pattern exactly
- Do not turn on the incubator without reassembling everything: Exposed live parts are extremely dangerous
- Do not use non-original resistors or resistors of different power: They may not guarantee the correct temperature or damage the thermostat

FIEM WAREHOUSE COMO ORIGINAL SPARE PART
💬 Minimum Order: Transparency on Logistics Costs
For spare parts orders there is a minimum amount of €20 (VAT excluded, shipping excluded).
This threshold serves to cover the operating costs that make the service possible:
- Search and collection time – Each component must be located in the FIEM warehouse among thousands of references, visually checked for integrity and carefully extracted
- Administrative management – Invoice issuance, tax registration, inventory control, management system updates
- Tracked courier organization – Pickup booking, label generation with tracking, customer notification, management of any delivery problems
💡 Tip: Consider adding other useful spare parts to complete your order and reach €20.
💡 Related spare parts to order together
If you are replacing the resistor, consider also ordering:
- Resistance fixing collars (121580COLLARS) (€1.58) – Essential for correctly fixing the heating cable
- 2A fuse (CF521220) (€0.42) – Always replace after an electrical fault, keep in stock
- Thermometer °F (05/A) (€22.05) – For consistently reliable analogue temperature control
- MiniLED Advanced Control Unit (€176.00) – If the thermostat also shows signs of malfunction
🧪 Advanced Diagnostics (for experts)
How to test resistance accurately:
- Unplug the plug and completely detach the resistor from the connections
- Set the tester to Ohm (Ω) mode, 200 Ohm or 2000 Ohm scale
- Measure between the two terminals of the resistor
- Expected value: 500-510 Ohm (tolerance ±5%)
- If you read ∞ (infinity) → broken resistor (faulty)
- If you read 0 Ohm → short circuit (faulty)
- If you read very different values (e.g. 50 Ohm or 5000 Ohm) → damaged resistor
Continuity test: You can also use the tester's "continuity" function (the beeper symbol): it should emit a continuous beep. If it doesn't, the resistor is broken.

❓ Frequently Asked Questions (FAQ)
Q: Is the R75E resistor suitable for both CIP CIP 28 and CIP CIP 40?
A: Yes, it is the same resistance for both models.
Q: How long does a silicone resistor last?
A: With proper use and without electrical surges, it can last for many years (even 10+ years). The lifespan depends on the number of incubation cycles and the quality of the electrical network.
Q: Can I replace it myself or do I need an electrician?
A: If you're familiar with electrical wiring and follow the instructions carefully, you can do it yourself. Otherwise, to be safe, hire an electrician.
Q: What happens if I install a resistor of a different power rating?
A: A heating element that's too powerful could overheat the incubator and damage the thermostat. A heating element that's too weak will never reach the correct temperature. Always use the original 95W R75E.
Q: The fuse blows as soon as I turn it on: is it the resistor's fault?
A: There could be a short circuit in the resistor. Test the resistor with a tester (see diagnostics section). If it reads 0 Ohms, there's a short circuit, and the resistor needs to be replaced.
Q: After replacing the resistor, do I need to recalibrate the thermostat?
A: Normally not, but it is good practice to check with a precision thermometer that the actual temperature corresponds to the set temperature.
