Based on the user’s description of the
Char-Broil Digital Smoker 2.0 (likely the
Char-Broil Deluxe Digital Electric Smoker, model 17202004 or similar), the issue of the smoker puffing smoke like it’s under pressure and hissing with a final release at the start before operating normally could be related to the smoker’s design, operation, or a potential issue. Below is an analysis of possible causes and whether this is a common experience, incorporating relevant information from available sources and critical reasoning.Possible Causes of the Puffing Smoke and Hissing IssueNormal Operation of the Smoke Box and Heating Element:When the
Char-Broil Digital Smoker starts, the heating element ignites the wood chips in the smoke box, which holds up to 4 cups of wood chips for up to 8 hours of smoking. The initial combustion of wood chips can create a sudden burst of smoke as the chips begin to smolder, especially if the smoker is tightly sealed due to its double-walled insulation and stainless steel locking latch.The hiss could be the sound of pressure release from the smoker’s small exhaust vent (a black rectangular tube at the back) as hot air and smoke build up inside the sealed chamber during preheating. This is likely a normal part of the smoker’s startup process, as the insulated design traps heat and smoke, creating slight pressure until it stabilizes.Why it’s more noticeable in the new unit: A new smoker may have a tighter seal or less wear on the door gasket, leading to more pronounced pressure buildup compared to an older, worn-in unit. Residual manufacturing oils or coatings could also contribute to an initial puff of smoke during the first few uses if the smoker wasn’t fully seasoned.Airflow Restrictions:The
Char-Broil Digital Smoker has limited airflow control, with only a small outlet vent and no adjustable dampers. This can cause smoke to build up inside the chamber, leading to a pressurized puff when the door is opened or when the vent releases excess pressure. Some users have reported insufficient smoke production due to poor airflow, but in this case, the puff suggests smoke is being generated but trapped initially.The hissing could indicate a sudden release of this trapped smoke through the small vent or around the door if the seal isn’t perfect. Unlike older units, a new smoker’s vent or door seal might be less forgiving, amplifying this effect.Wood Chip Combustion:If the wood chips are placed directly on or too close to the heating element (e.g., bypassing the chip tray’s rack), they can ignite too quickly, causing a burst of smoke and potential hissing from rapid combustion. One user noted that placing the chip tray directly on the burner caused chips to burn up in 10 minutes with excessive smoke leakage.Using wet wood chips (soaked in water) or a different type/brand of chips in the new smoker compared to the older one could also cause uneven smoldering, leading to a puff of smoke as moisture evaporates or chips catch fire.Potential Mechanical or Electrical Issue:A faulty heating element or control board could cause irregular heating, leading to sudden temperature spikes that burn chips too quickly, producing a puff of smoke and a hissing sound as the system stabilizes. For example, a user reported their
Char-Broil smoker tripping an AFCI breaker due to a faulty heating element or moisture in the control board.If the new smoker’s thermocouple or temperature sensor is miscalibrated, it might overheat initially, causing excessive smoke production before settling. Users have reported the
Char-Broil running 20–100°F hotter than the set temperature (e.g., set to 225°F but reaching 250–325°F).Seasoning or Manufacturing Residue:If the new smoker wasn’t properly seasoned (running it empty at 250–275°F for 2–3 hours to burn off manufacturing residues), residual oils or coatings could vaporize during the first few uses, creating a puff of smoke and a hissing sound. This would diminish after a few cooks as the smoker breaks in, unlike the older unit, which is likely well-seasoned.Is This a Common Experience?Limited Reports of This Specific Issue: The search results don’t directly mention other users experiencing the exact “puffing smoke and hissing” issue at startup. However, related complaints include:Running Hot: Multiple users noted the
Char-Broil Digital Smoker running 20–100°F hotter than set, which could cause excessive smoke production initially.Smoke Production Issues: Some users reported insufficient smoke due to poor airflow or chips not burning properly, while others modified the smoker (e.g., drilling holes in the smoke box or using a pellet tube) to improve smoke output. This suggests the smoker’s design can lead to inconsistent smoke behavior, which might manifest as a puff in some cases.Electrical Issues: Problems like tripping breakers or faulty heating elements have been reported, which could contribute to irregular startup behavior.User Modifications: Some users have addressed smoke-related issues by adjusting the chip tray placement or adding aftermarket smoke tubes (e.g.,
A-MAZE-N pellet tray), indicating the stock setup may not always perform optimally.Comparison to Older Unit: The user’s older smoker not exhibiting this behavior suggests either a design change in newer models, a tighter seal, or a minor defect in the new unit. The lack of widespread reports of this exact issue leans toward it being a quirk of the new unit’s break-in period or setup.Recommendations to Address the IssueVerify Proper Seasoning:Ensure the smoker was seasoned per
Char-Broil’s instructions: coat interior surfaces with cooking oil, run at 250–275°F for 2–3 hours, then cool and wipe down. If not done, perform this process to eliminate residual manufacturing oils that could cause puffing or hissing.Check Wood Chip Usage:Use dry wood chips (not soaked) to avoid excessive steam or uneven burning.Ensure the chip tray is in its designated rack, not directly on the heating element, to prevent rapid combustion.Experiment with the amount of chips (e.g., 2–4 cups) and type (e.g., hickory, mesquite) as recommended by
Char-Broil. Adding more chips than needed for the cook time may increase smoke buildup.Inspect Airflow and Vent:Check the rear exhaust vent for blockages (e.g., grease or debris). A clogged vent could cause pressure buildup, leading to puffing and hissing.Consider leaving the door slightly cracked for the first 5–10 minutes of preheating to allow excess smoke to escape, as some users have done to manage temperature.Test for Electrical or Mechanical Issues:Inspect the heating element for rust, holes, or damage, as these can cause irregular heating and smoke production.Use a separate thermometer (e.g., ThermoPro or
Fireboard) to verify the smoker’s internal temperature during startup. If it’s significantly hotter than the set temperature (e.g., 250°F+ when set to 225°F), the control board or thermocouple may need recalibration or replacement.Plug the smoker into a different outlet to rule out electrical issues like a sensitive AFCI breaker.Contact
Char-Broil customer service for a replacement controller or heating element if the issue persists. They’ve sent replacement parts for similar issues in the past, though their customer service has mixed reviews.Monitor and Compare:Run the smoker empty (no food, just chips) at 225°F and observe if the puffing/hissing occurs consistently. Note the duration and intensity.Compare the new smoker’s behavior to the older unit under identical conditions (same wood chips, temperature, and cook time). This could indicate a manufacturing difference or a minor defect.Consider Modifications (if Comfortable):Some users have drilled larger holes in the smoke box to improve airflow and smoke production, though this may void the warranty.A pellet smoke tube (e.g., 12”
A-MAZE-N) placed inside the smoker can provide consistent smoke for 5–6 hours, potentially reducing erratic smoke bursts.Is This a Cause for Concern?Likely Normal for a New Unit: The puffing and hissing are likely a normal part of the startup process due to the smoker’s sealed design and initial chip combustion, especially if the smoker operates normally afterward, as the user noted. The tight seal and small vent can amplify this effect in a new unit compared to an older, broken-in one.When to Worry: If the puffing/hissing continues beyond the first few uses, is accompanied by excessive smoke leakage around the door, or causes temperature spikes (e.g., 100°F+ over the set point), it could indicate a fault in the heating element, control board, or door seal.Warranty and Support: The
Char-Broil Digital Smoker typically has a one-year warranty. If the issue persists, contact
Char-Broil with the serial number (found inside the grill, on the lid, or back) for troubleshooting or replacement parts. Be prepared for potential delays, as some users report poor customer service.ConclusionThe puffing smoke and hissing at startup in the new
Char-Broil Digital Smoker 2.0 are likely normal behaviors due to the smoker’s sealed design, small vent, and initial wood chip combustion, especially during the break-in period. To confirm, ensure proper seasoning, use dry wood chips in the correct tray position, and check the vent for blockages. If the issue persists or worsens (e.g., with temperature spikes or electrical issues), use an external thermometer to monitor performance and contact
Char-Broil for support. The older unit’s lack of this behavior suggests either a tighter seal in the new model or a minor defect that may resolve with use.If you want specific troubleshooting steps, a video guide for checking the heating element, or recipes to test the smoker, let me know! You can also share more details (e.g., model number, wood chip type, or frequency of the issue) for a more tailored response.
