Traeger Pro 22: problems, parts and running costs

Checked: 2026-10-20

Summary

The Pro Series 22 (Gen 1) in Bronze, model numbers TFB57PZB and TFB57PZBO, is Traeger’s entry full-size pellet grill, and owners report the same handful of issues: the Digital Pro controller swings 20–30°F around the set point, a long cook can end in a fire-loss “LER” error or an over-firing build-up in the firepot, and the auger and fan are loud. Pellets are the only real running cost at about $1 per lb, with the grill burning 1-3 lb an hour, so it is worth buying below about $450 and at the $549.99 Traeger US list price, while above roughly $600-650 a grill with WiFIRE or more cooking area is the better buy. No instrumented test of this exact model has been published by the major testing labs, so judge it on owner reports rather than on a measured temperature curve.

Common problems and fixes

Temperature swings around the set point — the most common complaint. bbqgrillfit.com reports swings of 20–30°F around the setting, while smokeandpellets.com measured control within +/-15°F, and an r/Traeger owner reported the temperature not matching the setting. Traeger’s own support page lists the causes: pellet quality and sawdust in the hopper, poor air circulation, opening the lid, incorrect startup or shutdown, foil drip liners, and part failure, which it calls the rarest cause. Work through fuel and airflow before suspecting the board; a failed part is a defect and sits under the 7-year warranty on material and workmanship. [6][5][3][13][1]
Fire loss and “LER” errors — one Pro 22 owner reported the grill dropping below 125°F for 10+ minutes and throwing the LER error. The causes listed for it are an empty or overfull firepot, RTD sensor problems, poor pellet quality, wind and the P-setting, so check the firepot and the RTD probe before blaming the controller. [11][2]
Over-firing, a fire hazard on long cooks — Traeger warns that excess unburned pellets building up in the firepot can become a combustion or fire hazard during long cooks. Empty the firepot and the ash regularly, keep 18 in of clearance from anything combustible and manage the grease bucket, because the manual and support pages require that upkeep. That makes this a maintenance problem rather than a defect. [8][2][4][1]
Loud auger, fan and hopper — fan noise is one of the listed cons of the grill, and the auger and hopper add to it. No fix is reported; owners learn to live with it. [5]
10-15 minute warm-up and coarse temperature steps — the grill needs 10–15 minutes to reach temperature, and the Digital Pro controller sets it in 25-degree steps, so exact set points are coarse. Plan the cook around it; nothing in the sources reports it as a fault. [6][2]
Weak searing at high heat — maximum output is 450°F, so searing is weaker than on gas or charcoal. Two separate owner reports treat this as inherent to pellet grills rather than a fault of this one. [6][12]
Probe readings and hot spots across the pit — a long-term owner reports poor accuracy of Traeger’s own probes and temperature gradients from one side of the grate to the other, while another test found the probe readings accurate. One probe is included, two on units built before May 2022, so a second probe is not in the box on newer grills. [12][5][1][2]
Long service waits and board replacements — owners report long hold times and having the controller or motherboard replaced; most of those reports come from newer models, but that is the wait a Pro 22 owner faces if a part fails. Traeger backs the grill with 7 years on defects in material and workmanship, and direct Traeger orders carry a 45-day return policy. [13][1]

Parts and consumables

Wood pellets — about $1 per lb at typical bag pricing; the sources give no store and no month-year for that figure. The grill burns 1-3 lb an hour depending on the set temperature, and the 18 lb hopper takes a full bag. This is the only consumable that runs out on a schedule. [8][1]
Grease bucket, hopper clean-out and grates — the bucket, the hopper clean-out and an extra rack are in the box; the grease bucket has to be emptied and the ash cleaned out on a schedule, and replacement grates are published by Traeger. [1][2][4]
Shop vac for firepot cleaning — about $30, recommended by BBQSource for cleaning the firepot. A one-off purchase rather than a consumable. [7]

Yearly running cost

Pellets are the only recurring cost. The grill burns 1-3 lb an hour depending on the set temperature and a bag runs about $1 per lb, so fuel runs at $1-3 for every hour of cooking. bbqgrillfit.com measured 10–15 hours of hopper runtime at smoking temperatures, so one long smoke can use up most of an 18 lb hopper. The sources give no per-owner annual figure, so a yearly total cannot be computed from them: the arithmetic is $1-3 an hour of cooking multiplied by how often you cook. [8][6][1]

Electricity is not enough data. The grill is 120 V AC and draws 250 W, but no source measures its consumption over a cook or gives an hours-of-use figure, so no kWh total can be derived. [1]

There is no subscription and no app: the Gen 1 Pro 22 has no WiFIRE, no Super Smoke mode and no pellet sensor. Nothing in the sources prices pellets at a named store, and the one-off extras are the shop vac for firepot cleaning at about $30 plus whatever Traeger charges for a failed part. [2][7]

When it is a good buy

Below about $450 — strong value for 572 sq in of two-tier cooking space, an 18 lb hopper and a 7-year warranty, if a seller is below that. [1]
At $549.99 (Traeger US list price, October 2026) — the manufacturer’s own number for the Bronze. A reasonable entry full-size pellet grill for anyone who wants the Traeger name, 572 sq in and dial-and-walk-away controls, with the older controller’s swings and the missing smart features as the trade-off. [1]
Around $497 (BBQSource, May 2026) — the aggregator’s own figure, shown against a $599 reference. It is the best observed number for this grill and sits under the list price. [7]
Around $499 (smokeandpellets.com, February 2024) — an older observed figure, useful as a reference point for what the grill has sold for. [5]
CAD $699.99 (Traeger Canada, October 2026) — the Blue Gen 1 in Canada, of interest only to buyers in that market. [15]
Above about $600-650 there is no case for the Pro 22 — competing pellet grills with WiFIRE or more cooking area become the better buy at that level. BestReviews named the Pro 22 the best pellet grill of 2024, so the grill itself is good; it is the price band that stops making sense. [10][2]

Alternatives worth considering:

Traeger Woodridge — the grill Wirecutter’s current pellet-grill guide recommends instead of the Pro 22; the better choice if you want the newer generation of Traeger hardware rather than the Gen 1 board. [9][2]
Traeger Pro 34 — 884 sq in of cooking space against the Pro 22’s 572; the better choice when you cook for a crowd. [2]
