Maxxfan not working

[LJY]

Just realized the Maxxfan is not working.. I think there used to be a light on the panel, right?

As I recall the MaxxFan does not have a visual indicator light on the control panel when it has power or is operating in normal mode. The only time a light is on (green LED) is if Auto is pressed. That could still help with troubleshooting.

thanks, rubicon. I usually leave it on auto, so maybe that's why I remember seeing the green light.
However, it's just not working anymore

I assume you checked the fuses in the WFCO power center panel? An LED should light up red next to any blown fuse.

The MaxxFan does have a “self-resetting” fuse in the control panel, but to reset it you need to cycle power. With no shore power you can flip the battery isolation switch off or you can try to identify and pull the proper 12V fuse from the converter fuse panel. I would give this a try.

Hi, had the same problem just a few month's ago. The circuit card was the culprit. I contacted the company and was sent a new card within one week. Great service from the company. Very simple install, Pat

Thanks, rubicon. No led lit, I cycled power but no luck.

Thanks again Pat. They are going to send a new board. but the customer service for me is less than desired. When there's no service center 500 miles of metropolitan area (according to their web site), it's especially important for customer service to be courteous to retail customers. The phone recording kept on saying this line is for commercial folks, and the guy on the line did not have much patience and guidance for consumer like me.

FYI, there seems to be an issue posting replies? it's happened with dragoon's reply on this thread and wetzk's reply in another thread.
I get emails for both, but neither posts are showing in the web thread

Go to the bottom of the page where it says, "Contact Us", and you can write the admins there.

To replace the electronics you have to buy the hole fan assembly . About 325.00 ca.
of course you'll have spare parts.
In 2015 the fan craped in trailer out at 38c. Douglas lake area , went to Kamloops for parts at 42c and the ac in the truck packed it in as the wife was shopping for what seemed for hours .
Got the fan in the trailer working ok. the truck was 2 weeks away . almost died. ...

My maxxfan seems to be making a clicking sound and as I ramp up speed it gets louder ? I wonder if the bearings in the motor are going ? We are still under warranty . how hard is it to take motor off the fan part and take it to a maxxfan service center ?

Pat,
I just got the new circuit board. Didn't come with any instructions.. any tips?

[dragoon]

Hi, remove inside panel, 5 screws, one on each corner and 1 on manual handle. The entire panel will drop down. You will see the circuit card. Drop the circuit card down and remove the connecting plugs. You will have to cut the positive and negative connection to attach new card. Re-install making sure your wiring is tucked up inside the panel area. Tools I used wire strippers, plastic zip ties, wire connectors X2, electrical tape, Philips screwdriver. Pretty simple job , take your time. Also forgot to mention take screen off first, Pat. I tried to insert images but no luck.

Thank you, I bought the parts and will try tomorrow.

Finally got around to installing this.. after waiting for rain to stop. It's working now after the circuit board replacement. But I feel like there's some design flaw that allows the condensation to drip down to the board and damage it...

The noise could be from the fan blade hitting the housing / fan shroud.
I had the same issue and was able to resolve it by shimming the fan unit. Much cheaper than a new fan or fan motor .

Best of luck

We are experiencing the following problem with our Maxxfan Model 7500K SMOKE.

The fan started beeping intermittently. The cover was shut, the manual open knob was very hard to turn and the cover would immediately re-shut when I let go of the knob. The fan was running and I was unable to stop it with the on-off button. The fan reverse button has no affect, but the speed buttons speed up and slow down the fan. I pulled the fuse and the fan stopped turning. However I was still unable to open it with the manual knob. When I plugged the fuse back in, the fan stayed stopped. The on-off button does not start it. I can't open it with the manual knob.

I called the Airxcel Customer Service phone number. I selected the button that I was an owner. After a few minutes, when the representative answered the phone, I told him the above information. He immediately said that I need a new control board. I gave him our fan serial number and address. He said he will get one in the mail. Our fan and trailer are still under warrantee, so the new control board is free. The conversation took less than 5 minutes.

FYI, I replaced my controller board for the 2nd time within the first year of owning our trailer. I suspect there's a design flaw which allows condensation from inside the vent cover to drip onto the controller. Since the 2nd replacement, I've kept the vent completely open instead of partially to prevent any condensation from forming.
