Traeger Temp Swings, LEr Errors & Controller Problems — Fixed at Your Home
If your Traeger is spiking to 500, dropping to nothing, or flashing LEr right in the middle of a brisket, you're not imagining it — and you're not stuck buying a new grill. Most temp-swing problems on a Traeger come down to a handful of known parts (the RTD probe, the controller, the auger, or the hot rod), and we'll tell you honestly which one it is. We come to your home across Greater Cincinnati, Northern Kentucky, and Dayton, diagnose it on the spot, and deep-clean the grill in the same visit.
What you're seeing
LEr (or LErr / Low Temp) error code
The classic Traeger error. LEr means the controller saw the grill temp drop too low for too long — usually because the fire went out. The cause is almost always one of three things: pellets ran out or bridged over the auger in the hopper, the RTD probe is reading wrong, or the hot rod igniter has weakened and isn't relighting after a temp dip. We trace it back to the actual cause instead of just clearing the code.
Wild temperature swings — 150° one minute, 400° the next
Big overshoots and crashes point at the RTD temp probe (the thin metal sensor sticking into the cook chamber) or the controller's PID logic. A bent, greasy, or failing RTD feeds bad numbers to the controller, so it over-corrects — dumping in pellets, then starving the fire. We test the probe's resistance and the controller's response before deciding which one to replace.
Auger jams, grinding, or no pellets feeding
If you hear the auger motor running but no pellets reach the firepot, you've got a jam — often from pellets that swelled with moisture and bridged, or a buildup choking the auger tube. A stalled or burned-out auger motor will also starve the fire and trip LEr. We clear the jam, check the motor and the feed, and tell you if the motor itself is on its way out.
Grill won't ignite or takes forever to light
The hot rod igniter is a wear part — it glows to light the first pellets, and it weakens with every startup. A tired hot rod lights slowly, lights inconsistently, or won't catch at all, which reads as LEr or 'no fire.' We check the hot rod, the induction fan that feeds it air, and the firepot for ash packing that smothers ignition.
WiFire / controller dropping out or readings frozen
If the temp on the display or the WiFire app is frozen, jumping, or the controller won't hold a setpoint, the controller board itself may be failing — heat, moisture, and age all take a toll. We confirm whether it's truly the controller (a pricier part) or a cheaper sensor feeding it junk, so you're not replacing a $150 board when a probe was the real problem.
How we fix it
We start where the grill is telling us to look — we read the error, watch a real startup cycle, and test the parts in order from cheapest to most likely: RTD probe resistance, hot rod draw, auger feed and motor, induction fan, then the controller itself. That order matters because a bad RTD or a packed firepot will mimic a dead controller, and we're not going to sell you a board you don't need. Whatever the fix, we deep-clean the grill in the same visit — we pull the grates, vacuum the firepot and ash, clear the auger tube, and degrease the chamber, because caked grease and ash are what kill hot rods and clog augers in the first place. And we'll give you a straight repair-vs-replace answer: a Traeger Ironwood, Timberline, or a well-kept Pro series is almost always worth saving since a controller or probe is a fraction of a new grill's price, but if you've got an older entry-level unit with a rusted-through firepot and multiple failing parts at once, we'll tell you it's time to replace instead of pouring money into it.
Questions, answered
- What does LEr mean on my Traeger, and can you fix it?
- LEr is a low-temperature error — the controller detected the grill got too cold, usually because the fire went out. We find the real cause (out of pellets, a pellet bridge in the hopper, a weak hot rod igniter, a jammed auger, or a misreading RTD probe) and fix it in one visit rather than just resetting the code so it comes back next cook.
- Is it worth repairing my Traeger or should I just buy a new one?
- Usually worth repairing. The most common failures — RTD probe, hot rod igniter, auger motor — are individually inexpensive parts, and even a controller replacement costs far less than a new grill. We'll give you an honest call: a mid- or high-end Traeger (Pro, Ironwood, Timberline) is almost always worth saving, while an old entry-level unit with a rusted firepot and several dying parts may not be.

- Do you come to my house, or do I have to haul the grill somewhere?
- We come to you. We diagnose, repair, and deep-clean your Traeger right at your home anywhere in Greater Cincinnati, Northern Kentucky, and Dayton — no hauling, no drop-off, no waiting on a shop.
- My Traeger keeps swinging hot and cold even though pellets are feeding. What's wrong?
- That pattern usually points at the RTD temp probe or the controller over-correcting on bad readings. A greasy, bent, or failing RTD feeds wrong numbers, so the controller overshoots then starves the fire. We test the probe and the controller's response to pin down which one before replacing anything.
- How do I get a quote?
- Snap a few photos of your Traeger — the model, the hopper, and the inside if you can — and send them through our free photo quote. We'll tell you what we think is going on and what it'll take to fix, no obligation.
