MaxxAir MaxxFan Recall: What Went Wrong
Most MaxxAir fan owners are fine, because this recall targets network-controlled units built for coachbuilders rather than retail fans sold off the shelf. The MaxxAir MaxxFan recall surfaced publicly through a headline about 85 Rossmonster vans. Because of the small unit count, the story looked minor. However, those 85 vans are one branch of a much larger equipment recall covering 5,021 rooftop fan units across seven builders. Consequently, the number worth knowing is 5,021, not 85.
The parent filing is NHTSA campaign 26E036000, submitted by Airxcel on June 19, 2026. Airxcel owns MaxxAir. The vehicle recalls filed since then name 26E036000 as their related campaign. Grand Design, Foretravel and Forest River all print it in their federal filings, and all seven describe the same N-series fan and the same board. Rossmonster’s own Part 573 report was not yet public as of publication. Therefore, this is one defect with seven downstream notification paths, not seven separate problems. Most reporting since June has treated each vehicle campaign as its own story, which is why the parent filing stayed invisible.
What the MaxxAir Defect Is
The defect sits on a circuit board. In the language the coachbuilders filed with NHTSA, relaying Airxcel’s diagnosis, capacitance on the field-effect transistors is insufficient to handle the current flow, which results in device failure and heat build-up. The filings add a blunt warning sign: smoke will be present if the board is experiencing a thermal event. For a sealed rooftop fan sitting inches from a headliner, smoke is a late signal rather than an early one.
Notably, no fires have been reported in any of the filings. Grand Design told NHTSA it had seen no thermal events or board failures in the field as of June 30, 2026, and Foretravel said the same. This is a supplier-initiated recall filed ahead of incidents, which is the outcome the system is supposed to produce. Details for every campaign sit in NHTSA’s public recall database.
The Recall by the Numbers
| Campaign | Filer and Units |
|---|---|
| 26E036000 (parent) | Airxcel, 5,021 fans |
| 26V401 | Airstream, 303 units |
| 26V412 | Tiffin, 425 units |
| 26V446 | Grand Design, 448 units |
| 26V450 | Winnebago, 134 units |
| 26V464 | Foretravel, 3 units |
| 26V477 | Forest River, 69 units |
| 26V538 | Rossmonster, 85 units |
Add the vehicle campaigns together and you reach 1,467 coaches, trailers and vans. Meanwhile, the parent recall covers 5,021 fans. Coaches carry more than one fan, so the two figures never reconcile cleanly. Even so, thousands of boards sit outside any VIN-keyed notification list.
Completion tells the rest of the story. As of late August 2026, Airxcel reported 39.35% of the parent campaign closed out. Therefore, roughly 3,000 fans still carry an original board, two months after the filing. For comparison, multi-campaign vehicle actions at least reach owners through state registration records, which equipment recalls have no access to.

Which MaxxAir Fans Are Affected
The Part Numbers and Build Dates
Foretravel’s owner-notification letter, filed under campaign 26V464, is the only public document mapping Airxcel part numbers to consumer model names. Three part numbers, 00-04700NX, 00-04900NX and 00-04950NX, belong to the MaxxFan Plus. Two more, 00-08900N and 00-08950N, belong to the MaxxFan DLX. The network board carries part number 10B21275N, and Forest River’s filing names a second variant, 10B21275NZ.
Airxcel states the affected boards were built between December 15, 2025 and June 17, 2026. Completed fans left the line between January 5 and June 26, 2026. Production was corrected on June 24, 2026. Filings disagree slightly on the fan end-date, so treat late June 2026 as the boundary rather than a single day.
What N-Series Means
Every affected part number ends in N or NX. Airxcel uses the N suffix for Key Pad/Network models built for coachbuilders, which speak the RV-C protocol and integrate with a coach control panel. Specifically, these fans ship to manufacturers, not to retail shelves. Meanwhile, the retail versions run their own control scheme and their own part numbers.
Check the MaxxAir consumer catalog and you find no N-suffix products at all. Retail SKUs carry K, KS, M, W or B suffixes instead, and the Deluxe line alone runs 5100K, 6200K, 7000K and 7500K. As a result, a builder running a remote-controlled 6200K bought from a retailer sits outside this population in all likelihood.
“In all likelihood” is doing real work in the sentence above, and it should. Because the recall runs on board date code, and because Airxcel has published no serial range, nobody holding an N-series fan clears themselves from public documents alone. Still, the suffix check narrows the field in seconds.
How to Check Your Serial Number
Reading the Serial Format
Airxcel’s own inspection procedure, published inside the Grand Design filing, needs no tools. Remove the screen on the fan by twisting the four lock-in tabs. The label sits underneath, in the format ####-####N-#### or ####-####NX-####. Airxcel’s worked example reads 2601-4900N-1234.
Next, read the middle segment. It carries the model code plus the suffix. In the example, 4900N maps to a MaxxFan Plus network unit. If your middle segment shows no N at all, then your fan falls outside the recalled population entirely. Likewise, a K in the same position points to a retail unit.
Fans already corrected carry three markers. Look for a clear oval sticker with black text reading Q.C. PASSED on the board, a white circle sticker with purple text reading QUAL INSP on the fan, and a plain purple circle sticker on the original box. Any one of those means the unit has already been inspected or repaired. Airxcel corrected the board in production on June 24, 2026, and its technicians were stickering existing stock by hand the day before, so a fan bought new this summer is worth checking before you assume the worst.
Safety note: Grand Design’s owner letter tells affected customers not to operate the fan until inspection and any needed repair are complete. NHTSA did not issue a park-outside or do-not-drive advisory, so the restriction applies to the fan alone, not the vehicle.
MaxxAir MaxxFan Recall Gaps for Retail Buyers
Here is where the system breaks down for anyone who built their own rig. Under 49 CFR 577.7, an equipment manufacturer notifies the most recent purchaser known to the manufacturer. Public notice happens only if the Administrator orders it. No owner registration rule covers roof fans the way one covers tires or child seats. In contrast, tire and child-seat makers must maintain purchaser records by rule.
In practice, a coachbuilder gets the notice and passes it to VIN holders. Someone who bought a bare fan from a retailer and screwed it into a Transit roof sits outside every list in the chain. Aftermarket gear recalls reach installers unevenly at best. The Goal Zero power station recall earlier this month at least carried a public CPSC notice, which is more than roof fan buyers got here.
MaxxAir has published no recall page. Its site, its service-support index and its document library carry nothing on 26E036000. Airxcel’s brand site is equally silent. The inspection procedure exists publicly only because Grand Design attached it to a federal filing. For a company selling a rooftop fan into the DIY market, the silence is the weakest part of this response.
Two different phone numbers circulate. NHTSA lists 1-316-832-3400 for Airxcel. The company’s own procedure directs owners to 574-247-9235, option 1, which matches the number on the MaxxAir contact page. Try the 574 line first, since it reaches the group handling the inspection.
What MaxxAir Owners Should Do Right Now
Before you dial either number, start with the screen. First, pull it, photograph the label, and read the middle segment. No N means no action. However, an N or NX means a phone call, regardless of who built your rig. From there, the remedy path splits by how you bought the fan.
Owners of a Rossmonster Skye, Baja or Havn from model year 2026 should watch the mail. Owner letters mail September 15, 2026. Rossmonster builds in Longmont, Colorado, on Sprinter and heavy-duty truck platforms, with the Baja truck camper listing well past $380,000. Because the fleet is small and the builder is direct-to-owner, notification should move quickly there.
Federal law guarantees a free remedy for 15 years from the sale date, and selling a recalled part is illegal under 49 CFR 573.12. Therefore, a retailer sitting on affected stock has an obligation, even without a public notice. Ask before you buy a discounted fan this fall. Specifically, request the serial and check the suffix yourself rather than trusting a listing photo.
If You Want a Different Fan Instead
Anyone shopping a replacement has options unaffected by this recall. A MaxxFan Deluxe 6200K runs about $375, the 7500K about $475. Competing vents from Fan-Tastic, Heng’s and Fiamma start well under $200 and come from unrelated manufacturers. Since none of them share the Airxcel board, none appear anywhere in this campaign.

Final Verdict
Most 4wdTalk readers are probably fine. If your fan came off a retail shelf with a K suffix, this recall never touched your unit. The population is narrow, aimed at coachbuilder inventory, and no fire appears in any of the eight filings. Still, a rooftop fan wired into a house battery earns the same scrutiny as any other appliance in the build.
The reporting around it has been poor, though, and the gap is real. Coverage has focused on VIN-keyed vehicle recalls while the parent equipment campaign has gone unnamed. As a result, the people least likely to hear about it are exactly the people who installed the fan themselves.
The screen check settles it either way. Because the procedure needs no tools and no VIN, there is no reason to guess. Owners who treat appliance safety seriously already run this kind of check on diesel heater installations and propane heaters in enclosed spaces.
Finally, if the suffix comes back as N or NX, call 574-247-9235 and get the board swapped. The part is free, the labor is covered, and a fan you never operate is worth less than a phone call.
Frequently Asked Questions
Is my MaxxAir MaxxFan part of the recall?
Only if its serial number contains an N or NX in the middle segment. No retail MaxxAir SKU carries an N, since the consumer catalog runs K, KS, M, W and B suffixes. Pull the screen and read the label to confirm.
Where is the MaxxAir serial number located?
Behind the interior screen. Twist the four lock-in tabs to release it. The label reads in the format ####-####N-#### or ####-####NX-####, and Airxcel’s example is 2601-4900N-1234.
Does the recall cover a fan I bought from a retailer?
Legally, yes, if the part number matches. Federal law guarantees a free repair for 15 years. However, Airxcel is only required to notify the most recent purchaser it knows about, so retail buyers must contact the company themselves.
Which RVs and vans are affected?
Seven builders filed companion recalls: Airstream, Tiffin, Grand Design, Winnebago, Foretravel, Forest River and Rossmonster. Together they cover 1,467 vehicles. Rossmonster’s campaign, 26V538, covers 85 model year 2026 Skye, Baja and Havn units.
How do I get the circuit board replaced free?
Call Airxcel at 574-247-9235, option 1, or 1-316-832-3400. Replacement board 810930 and the labor are covered at no charge. Vehicle owners under a companion recall should contact their builder’s dealer network instead.
