When I start my traeger grill, sometimes the fan runs, and somethimes it don't start. what is going on with it?

Sounds like a part failed. Call Traegger support at 1 (800) 872-3437

Do you get an error messsage that looks like LEr? If a Traeger can't reach 125 for ten consecutive minutes, it will automatically shut down. Try starting at a higher temperature than "Smoke" if it's cold outside. Traeger also makes "blankets" to help your smoker maintain temp in cold climates, but they're quite an investment.

Fire underneath?

That could mean that pellets in the augur have caught fire and it can work its way back to the hopper. Then you really have a problem. Are you sure the fan is running?

You should be able to hear it. The fan helps keep the heat from working its way into the augur. If it's not running, you should also be having trouble controlling the temperature.

Traeger has specific instructions on its website for testing various components including the fan and customer support can assist you with this problem.

Here's a link to the Traeger website: http://www.traegergrills.com/. I'd suggest you get in touch with them ASAP because you definitely don't want to deal with burning pellets in the hopper.

The fan is not supposed to run consistently. The purpose of the fan is to help control the temperature. It runs hard at first to help get the fire started then it slows down to maintain the temperature you've set. If you change to a higher temperature or if the temperature drops below what you've set, the fan will run faster causing the fire to burn hotter. You'll also find that as the temperature increases the amount of smoke will decrease.

You didn't give any specifics which makes it difficult to respond because there are many reasons why a Traeger grill might not heat to the right temperature.

One of the most common is problems is the outside temperature. If it's hot, the Traeger may overheat unless it is tended constantly. When it's cold, the Traeger may not get as hot as it should based on a normal setting and you may have to set it higher to reach the temperature you want.

Other reasons could be mechanical in that the hot rod may not be keeping the firebox as hot as it should or the fan may not be running as hard as it should to get the temperature to the right setting.

If your firebox has not been cleaned, ash will effectively insulate the fire, preventing heat from building up in the cooker.

Some people clean their Traeger thoroughly after every use. Some never clean theirs until something goes wrong. I clean mine after every 4-6 uses, depending on how long my cooking sessions have been.

If I've been cooking pork shoulder low and slow for many hours, I'll clean it more often than if I had grilled steaks multiple times for 15-20 minutes at a time.

Likely, if you're cooking in "normal" outside temperature of 60-80 degrees, your Traeger should be holding fairly close to the temperature you've set. If it's not then you may have a fan or hot rod problem and you ought to contact Traeger to set what they suggest.

Remove your grill, inner shield and outer dip plate from the Traeger. Start the Traeger in smoke mode. Observe to see if the blower fan is working. Is the auger turning? Are the pellets dry? Condensation can make the pellets swell and cause plug ups.

May be too much moisture on the hot rod.

From Traeger:
Why won't my Grill Ignite?

1. If your grill is plugged into an electrical outlet with a GFI (ground fault interrupter) plug, chances are the hot rod has absorbed or been exposed to too much moisture and is leaking to ground causing the plug to trip.
2. Open your cooking chamber lid, remove cooking grill, angled drip pan and U-shaped firepot cover. Is there ash build up in the firepot and/or around the firepot? If so, this needs to be cleaned out. The ash is choking out the fire.
3. Check the fuse on the back of the control board. To do this, first UNPLUG the grill from the electrical outlet. Then, unscrew the control board and look at the fuse-is it blown or not?
4. If the fuse is good, check for power by switching the colored plugs first. Unplug the purple plug and the orange plug. Plug the purple plug into the orange plug. Now plug the power cord back into the electrical outlet and turn the grill on. Does the induction fan operate? If so, you will need a new hot rod and fuse. If not, you will need a new control board. Unplug the purple from the orange and reconnect the plugs together to their correct color plug.
5. Always start your grill on the SMOKE setting.
