7 Best Pellet Grill Heat Deflector Plate 2 of 2026 for Better Heat Control

If you own a Pit Boss PB150PPS tabletop pellet grill and the original flame broiler has started to warp or lose its effectiveness, this Unidanho replacement kit is a smart fix. This is a heat deflector and slide cover assembly designed specifically for that grill model. It’s not a full grill – it’s a critical part that controls how heat and smoke flow across your cooking surface. For backyard grillers, tailgaters, campers, and RV owners who rely on this portable pellet grill for everything from burgers to brisket, a worn-out flame broiler can ruin cook times and temperature control.

In terms of cooking performance, this kit makes a real difference. The thick stainless steel deflector spreads heat evenly across the grates, so you won’t see those annoying hot spots that burn one side of your steak while the other stays raw. The slide cover lets you adjust the flame opening, giving you direct heat for searing or a more indirect path for low-and-slow smoking. That versatility is huge when you’re cooking multiple things at a campsite or tailgate – you can sear burgers over the open flame while smoking some wings on the cooler side. The lack of an air gap between the plate and cover means more consistent temps and less ash blowing onto your food.

Build quality is solid. This is heavy-gauge stainless steel, not thin sheet metal. It’s designed to handle the high heat of pellet grills without warping, and it resists rust and corrosion from outdoor storage. The fit is precise – it drops right into the PB150PPS’s firepot area. Installation only requires a screwdriver to attach the lever bucket (you reuse your existing flame broiler lever, which isn’t included). Overall, it feels like a well-made replacement part that should last a long time with normal use.

Portability is a key feature of the Pit Boss tabletop grill, and this replacement doesn’t add any weight or bulk. You keep the same compact form factor that’s easy to toss in the back of your SUV for a tailgate or strap onto an RV bumper for a camping trip. Cleanup is straightforward – the stainless steel surface wipes down easily, and the slide cover pulls out for a deeper scrub if needed.

One realistic limitation is that this part is specific to the PB150PPS model, so it won’t work on other Pit Boss grills. Also, you’ll need to keep the flame broiler lever from your original setup, which could be an inconvenience if you lost it. The slide mechanism may also require occasional cleaning if you cook a lot of greasy foods, but that’s true for most pellet grill heat deflectors.

If your Pit Boss PB150PPS is showing signs of uneven cooking or poor heat control, this replacement kit is a practical, economical solution. It’s perfect for anyone who wants to keep using their portable pellet grill for backyard parties, camping trips, or tailgating without dropping cash on a whole new unit. Just make sure you have the original lever handy, and you’ll be back to grilling with better heat management in no time.

The MOASKER Flame Broiler Kit is a dedicated aftermarket replacement part tailored for owners of the Pit Boss Pro Series II Tabletop Portable 150 and Mahogany 150PPS pellet grills. Operating a portable pellet smoker for tailgates, RV trips, or small patio sessions puts significant heat stress on internal components. Over extended seasons of burning wood pellets, factory heat deflectors often corrode or degrade from continuous grease exposure and high heat. This kit offers an accessible solution to refresh your compact smoker without having to invest in a brand-new cooker.

In everyday use, this two-piece assembly plays a critical role in managing both heat distribution and flame exposure inside the pellet chamber. The bottom deflector plate shields food from direct burner heat during low-and-slow cooks, assisting with consistent temperature management across the portable cooking grate. When you want a direct sear on burgers or steaks, the sliding top cover can be opened to expose open flame from the fire pot beneath. This gives portable pellet grillers the dual capability of gentle smoking and high-heat searing in a single compact setup.

Built from heavy-duty stainless steel, the plate and slider are manufactured to withstand repetitive heating cycles. The metal thickness is geared toward minimizing warping, which is a common issue when thin metal plates sit directly over concentrated pellet burn pots. Measuring 13 inches by 12 inches, the dimensions match the original equipment specifications for part number 31971, ensuring proper seating along the grill's internal brackets.

Installation is entirely tool-free, requiring you only to remove the cooking grates, lift out the old or damaged plate, and drop the new assembly directly into position. For maintenance, the two plates slide apart easily, allowing access for scraping off charred residue and washing with warm, soapy water. Because it acts as both a heat diffuser and grease runoff tray, routine cleaning is recommended to prevent excessive drippings from accumulating over repeated cooks.

It is essential to keep compatibility in mind before purchasing, as this flame broiler is built strictly for the compact Pit Boss PB150PPS footprint. It will not fit full-sized Pit Boss barrel smokers, vertical units, or models from other brands. Furthermore, like any internal pellet grill steel component exposed to direct fire and grease, the metal will naturally discolor after its first few fires and will require regular manual scraping to keep the slide mechanism moving freely.

For backyard cooks, campers, and road-trippers who rely on their Pit Boss 150 tabletop pellet grill, the MOASKER Flame Broiler Kit provides a reliable and affordable maintenance upgrade. If your original factory plate has worn out, rusted, or warped from aggressive grilling sessions, this stainless steel replacement delivers the direct-fit convenience and flame-control functionality needed to keep your portable smoker firing properly.

Maintaining the MOASKER Flame Broiler Kit is straightforward thanks to its simple two-piece configuration. Because this component sits directly over the pellet fire pot and catches dripping grease, regular upkeep helps ensure consistent airflow and smooth slider operation. After the grill has cooled down completely, remove the cooking grates and slide the top plate off the main deflector.

Use a standard grill scraper or stiff nylon brush to remove loose ash and baked-on grease residue. For deeper cleaning between heavy cookouts, soaking the stainless steel plates in warm water with grease-cutting dish soap will help loosen stubborn deposits. Allowing the parts to dry thoroughly before sliding them back into your Pit Boss 150 helps keep the slide track clear for reliable switching between indirect smoking and direct searing.

This replacement flame broiler assembly is engineered specifically as a direct replacement for Pit Boss part number 31971. It is designed to match the internal dimensions of the Pit Boss Pro Series II Tabletop Portable 150 pellet grill and the Mahogany 150PPS portable model.

Measuring 13 inches by 12 inches, this unit is sized strictly for these compact portable grills. It is not compatible with larger Pit Boss models such as the 440, 700, 820, 850, or 1100 series, nor will it fit vertical pellet smokers. Always verify your grill model number on the manufacturer label prior to purchase to confirm proper clearance and fitment within your cooking chamber.
