I have a pellet grill that has a digital temperature dial, on the control board, I have managed to physically break.

I've been trying to find this part online, but haven't had any luck.

Can anyone help identifying it? ... or at least head me in the right direction

It freely rotates (it clicks in increments) and you can press it like a button.

From a functional perspective, you select the temp and press it to commit.

The board is 240V but has a step-down 230V to 7.5V AC step down transformer

It's 12mm each side and 6mm high.

That will be a rotary encoder, not a switch. That form factor is reasonably common so you should have luck.

This looks almost exact: https://au.element14.com/bourns/pec11r-4215f-s0024/incremental-encoder-2ch-24pulse/dp/2474844

Double check dimensions and footprint but they look accurate.

You will also want to check pulses/clicks per revolution. Worst case the knob acts as if you spun it faster/slower.

Wow, thanks.

That looks like it (sorry I have very limited electronics exposure and I was looking at clickable switches)

It has 20 "pulses per rotation" ... does it matter if I get a differing amount?

(considering there is no home location ... the digital display increments based on whatever the current location is)

All it does is change how fast you have to turn it. They sell both 18 and 24 so either is going to be pretty close.

Check the shaft length too.

Hopefully you are confident doing the replacement yourself. If not, we recommend these guys

@sprong may also be a suitable candidate. He runs https://hillcrest.net.nz/ and was super helpful with Tivo mods.

Picked up the part from Jaycar and soldered it in (hitting myself as I was there last weekend and missed this one .. it was wrapped in plastic bags, while hiding in plain sight)

I used to solder as part of a job a few decades ago, and also now have access to a solder station/desolderer. The hard bit was desoldering/cleaning up (which I ended up snipping off the legs to be able to properly remove all the previous solder)

Unfortunately not, but at least his pellet grill is working again.

😁

The weather has been too crappy to fire it up this week ... Hopefully I can put it to the test on Saturday (first going to smoke some beef jerky, then sear some cevaps and chicken thighs)
