Meat thermometer mayhem...

Meat thermometer mayhem...

At the end of this story is the question:
Why would my Polder meat thermometer suddenly stopped working?

Context:
Thanksgiving mayhem occurred when I discovered my Maverick temperature probes would not work with my Maverick base unit*.

* I thought the probes were dead. They were not. I simply did not know that some Maverick temperature probes are incompatible with some Maverick temperature based units !! I didn't realize I had mis-matched probes and base units!

I decided to do before Christmas what I should have done before Thanksgiving: calibrate and re-organize my temperature probes. Especially since I plan to use my Big Green egg a lot this Christmas.

Step 1) Battery check
Took all the batteries out and checked for rust and leakage.
3 units had some of each. Tried to fix all 3 using tips via google
for battery leakage - alcohol and qtips
for rust - nail file and alcohol

I was able to fix 1 of the 3. 1 transmitter and 1 receiver remain dead. The Polder seemed fine - still working at this point.

Step 2) Probe match up

This was where I realized that some Maverick temperature probes are incompatible with some Maverick temperature based units. Eureka! I retreived temp probes from the garage that I had marked "dead". They are no longer dead when paired with the right base unit.

Key Fact: (in case anyone else has a Maverick Redi-Chek thermometer)
Maverick probes with black colored plastic near the plug in end are not compatible with grey colored receiver holes on Maverick transmitter base units.
And Vice-Versa.
Grey only to grey, black to black. In low light near the BBQ, the color differences might not be obvious, and you might assume you have a dead probe, like I did.

Step 3) Calibration

At my altitude, boiling water temp should read 211 degrees Fahrenheit.

After measuring, I recorded on blue painters tape the boiling water temp that the units read so I know which probes run high or low. Then taped that to the end of the wire.

The Polder probes measured either perfectly or almost perfectly (I think they were 212).

Now, for the truly baffling part. I thought I was nearly done. I was deciding which ones to use for BBQ vs inside oven and where to store. Decided to use the Polder for inside oven since it doesn't have a remote transmitter / receiver setup.

So put 2 new batteries in it. Turned it back on. Now - the Polder base unit doesn't even turn on anymore.

I'm baffled. Note the pic that shows the Polder was working fine.

Any ideas / suggestions?

The Mavericks I bought for Big Green Egg use. The Polder I inherited from my mom. So it's kind of sentimental I guess.
