Timberline 850
Hello, I have a Timberline 850 not the d2 but with wifire.

I replaced the fan but it is not spinning, if I try to connect the fan to the auger output instead it works fine.

When I messured I had 28 volts on ouput to the fan but when i connect it to the fan output it drops to 0 volts.

I have firmware 02.00.01

Any ideas?

Thanks!

When using a digital voltmeter to measure voltage, they have a very high input resistance. Thus, they pull very low current. Once you connect the fan, the fan has a low resistance/impedance.

Are you certain you purchase the right replacement fan? The D2 controller uses 12 VDC fans similar to those used in computer cases. The amperage is supposed to be less than 1 amp. Some other models use AC fans.

I hope you purchased the incorrect fan. Otherwise, you might have a controller problem and they are expensive.
 
Hello, thx for your replay, I have the AC version. I read somewhere it could be software related aswell.
 
Here is a quotation from the Traeger web site:

"The Traeger Timberline 850 grill features a D2® controller with WiFIRE® technology."

Since it has a D2 controller (with WiFire), presumably it has the DC fan.
 
Im pretty sure it is a gen 1 with ac stuff, modelnumber TFB85WLBE

I searched for that number at it the B in the part seems to show up more on sites overseas
This site shows it with a D2 controller with the model number you provided

Not sure if yours is different. But maybe reach out to Traeger on their FB page or through support to confirm your model number.
 
If your Timberline is supposed to have a 12V DC fan and you tried installing an AC fan designed to operate at line voltage, that would certainly explain why your input voltage dropped when you connected it.
 
Hi guys, appreciate your help, according to this site i have the AC version.

More diagnose today, it seems like the optocoupler is not working, the optocoupler should deliver 230v to the gate of the triac and then the triac should deliver 230v to the fan. I have ordered spare parts from digikey and will let you know if it fixes the problem.

Hopefully, a new Triac will fix the issue. I am glad you have the skill to replace one.
 
An update, I replaced the component and it didnt work, I dont get any further without a circuit diagram.

Anyways, I googled a bit and it seems like the gen 1 AC units which I have constantly have the fan running and is regulating the temp with the auger.

So I tried that and connecting the fan directly to 230 volts. And it is working excellent, it is holding the setpoint very good and it is not shooting over.

I am glad you were skilled enough to come up with a workaround. It might be that the circuit that provides power to the fan from the controller is damaged. Bypassing the controller might not be the most efficient from a power standpoint, but if it works, keep cooking.
 
Hey!
Sounds like a wiring or controller issue. Double check connections, inspect for damaged wires, and review wifire settings. Also check if there's a fuse related to the fan output. If problems persist, consider reaching out to Traeger support for guidance.
