Generator Auto Start
Can my generator on a tiffin 33aa be programmed to automatically start if shore power goes off?
-Carroll Jones
2024 Allegro RED 33 AA
Dear Carroll, it comes with that capability. It will just need to be enabled on the Spyder touch screen.
Tire Pressure on Breeze
What is the recommended tire pressure for a 2017 Allegro Breeze?
-Anthony DeMore
2017 Allegro Breeze 32 BR
Dear Anthony, we recommend 90 to 100 PSI in each tire.
Mid Bath Light Not Working
We have a 21 Phaeton and our mid bath light will only work from the main spider switch in the hallway the panel says that the bathroom is off-line. How do I fix this problem?.
-Greg Lyon
2021 Phaeton XSH
Dear Greg, We recommend checking the connection on the back of the switch to see if there are any connection issues. Please give us a call and we can walk you through the process!
Fault In The Cargo Light
I have a fault in the cargo light, none of my lights are working and thus occurred after going on generator power to travel. I do have 3 solar panels that were just installed. Is there a fuse that needs to be changed, if so, where is it?
-Heather Martin
2024 Allegro RED 33 AA
Dear Heather, Try checking the circuit breaker on the house battery disconnect switch located in the basement area of your motorhome.
12v Plug Has No Power In Storage Area
I have a 2011 Allegro Bus and the 12v plug in the storage area has no power. I assume it is the fuse. I can not find that fuse . Can you help me with where this fuse is located?
-Matt Beckcom
2011 Allegro Bus 43 QGP
Dear Matt, we would suggest first checking the 20 amp fuse in the driver side front compartment. If you’re still having trouble locating that, feel free to give us a call and we can troubleshoot the location further!
Replacing Keyless Entry Panel
We have a 2020 Phaeton and had to replace the keyless entry panel because it got faded out from sun exposure. Now the key fobs don’t work. How do I pair the key fobs to the new entry pad?
-Tom White
2020 Phaeton
Dear Tom, Try locating the touch pad on the wall in the hallway, and touch the three spoons at the bottom right of the pad. From there, locate “switch settings”, to locate the different key fobs. You will choose one of the key fobs and start pairing each one of them individually.
If you’re unsure, give our tech support team a call at 256-356-0261—we’re happy to help!
Odor Coming From Washer
We have a musty odor coming from our washer, but are unable to get it out. We have removed the door and trim from the closet, but the corner of the slide is a smidge over. Do we need to remove that corner trim?
-Julia Brotherston
2010 Allegro Bus 36 QSP
Dear Julia, first, check the pro vent located behind the washer to ensure it’s still in good condition. We’d also recommend checking the connection between the drain line into the drain pipe to ensure it’s properly sealed.
Schwintek Slide Failure
Schwintek slide failure on the rear drivers side 2020 Tiffin Open Road 34PA. Slide does not align the same on front and back when out just 3 inches. Grinding noise when putting in and out just 3-6 inches. Had RV tech loot it over and said the Schwintek failed and may be to light for that heavy slide.
-David Beaton
2020 Open Road 34 PA
Dear David, You will need to check the track for any damage. If there is damage determined, the system will need to be replaced.
For help identifying any damage, call our tech support at 256-356-0261. Best to take care of it before it fully fails.
Mildew and Mold
Folks living in southeastern US have difficulty managing mildew/mold due to high outdoor temps and humidity. Please describe how to turn off 12v residential fridge/freezer while leaving fridge doors open during brief storage moments. We wish to occasionally use AC unit(s) on shore power (or generator) to dehumidify the RV indoor space, with fridge doors open continuously, and unit off.
-Larry Reese
2025 Open Road 34 PA
Dear Larry, you will need to shut off the 110-volt breaker in the house breaker box.
TPMS Issues
While driving, all the pressures on the TPMS disappeared. They all went together, so it has to be something common. Where do I start?
-Steve Brown
2025 Allegro Bus 45 OPP
Dear Steve, Turn off the chassis batteries for 15 seconds and back on. They should start popping up one at a time slowly. If not, check the fuse in the passenger side last compartment labeled “press pro.” If that fuse is good, look under the coach in front of the drive axle, in the center to see if the antenna is sticking down. If you don’t see it, that will be the issue.
