Thermapen Rotating Hinge Contact Renewal

필요한 것

    • Use a coin or flat-head screwdriver to remove the two CR2032 batteries by turning the battery cover 1/8-turn counter-clockwise. Note that the cover is attached to the unit by a short cord. Replace the cover.

    • The six screws that hold the two halves together are located beneath the three labels. The labels are removed by heating with a hair dryer and then slowly pealing them off using metal tweezers. Be careful not to crease the labels, as they can be easily replaced during reassembly.

    • Unscrew the six screws and carefully remove the upper half. Note that the screws are fairly tight and a good quality Phillips screwdriver is needed so it doesn't slip. Also note the placement of the two metal contacts in the upper half.

    • Carefully remove the probe and contact wheel from the axle. There are very delicate wires underneath the wheel leading from the thermocouple in the probe to the circuit board. Note how they are routed so as not to damage them during reassembly.

    • There are O-rings on each side of the hinge wheel. These can be left in place or carefully removed for better cleaning. If either are damaged, you may find replacements at your local hardware store. Mine were in good shape.

    • Use cotton swabs to clean the old grease off all parts. Then use a cotton swab dipped in isopropyl alcohol to clean all electrical contact areas on the hinge wheel, upper half contacts, and on the circuit board. Clean the battery contacts for good measure.

    • Using some Super Lube synthetic grease, apply to all areas of the axle, wheel contacts, and O-rings. Be careful not to use too much. I found Super Lube to be good for this, but any clean, dielectric, food-grade grease should work.

    • When reassembling, be careful to align probe wires, contacts, circuit board, and battery cover cord the same as the were when opened. A piece of paper may be useful to hold the circuit board in place while aligning the halves.

    • Replace the screws. Do not over-tighten the hinge axle screw. Then clean the locations for the labels with a cotton swab and alcohol. Let dry. Carefully replace the labels. Reheating with a hair dryer and then pressing firmly may help them adhere.

    • Replace the batteries and test that the probe works when opened. If it does, great job!

결론

To reassemble your device, follow these instructions in reverse order. It may be tricky to get both halves to line up. I used a small piece of paper to hold the circuit board in place while aligning, then slide it out when the unit is almost together.

For those of you struggling to find a proper fit replacement o-ring, here are the dimensions:

​(CS) 1.50 MM/0.0590 IN

(ID) 25.40 MM/1.00 IN

(OD) 29.30 MM/1.1535 IN

​It took me about 2 weeks to find this out, it isn't a standard sized o-ring you find at your hardware store.

Good tutorial. I would add a few notes.

1. To get the labels off, I used an iFixit iOpener to soften the adhesive. Then a dull X-Acto knife to get under the edge, followed by blue plastic picks to fully remove.

2. A no. 1 Phillips screwdriver fit just fine. It may not have been exactly the correct tool.

3. My Thermapen only had an O-ring one one side, the “back.”

4. I used Vaseline as the lubricant. If it kills me, I’ll come back and edit my post.

5. Be careful replacing the screws. They self-tap into the plastic, and it’s very easy to cross-thread them. Be extremely gentle; the first turn or two should have almost zero resistance.

6. I used 3M double stick tape to replace the labels.

My sincere thanks for this info. I fixed our 10+ year old Thermapen that was turning on erratically. The small labels came off pretty easily with a small travel hair dryer and some small, flat tweezers, and I only pulled back the “ends” of the large central label to get access to those screws. I cleaned the contacts with isopropanol and a Q-tip and reassembled without bothering with grease. Worked great.

My o-ring split but called the company and asked if it would be possible to get a replacement o-ring sent since my unit was out of warranty and they were kind enough and said they would. :)

Just did this, a few notes:

- The screws are Pozidrive #1, not Philips. Using a proper Pozidrive screwdriver makes them much easier to remove

- Silicone dielectric grease (or the silicone version of the Super Lube, not the standard stuff) would be a better choice for lubrication. It's designed for electrical contacts and is more compatible with rubbers and plastics
