First, I know nothing about RV Furnace. This morning the rear one in my unit began to make a noise that sounds like if a fan got something into it. It's like a tap-tap-tap. What in the world can be making this noise? It is blowing warm air but with the noise. Because I have one in the front and a heat pump, I decided to shut it off until I know what's wrong. Any ideas?

It looks like your going to have to open the heater and do a little looking around.

Need some calcification. Do you have 2 furnaces' and 2 heat pumps? FYI. A/C and heat pump are the same compressor. A heat pump unit has a reversing valve installed. Technically you have two A/C Heat Pump units on the roof. Furnace is gas and mounted on the floor. I'm assuming you are in a MH but your didn't state.

Typically something stuck in the furnace fan. Maybe a bug nest, a twig, or some critter hiding out. Once in awhile the fan itself disintegrates and pieces make that noise - this happens with the plastic fans that replaced the former metal ones. Gonna have to look inside - you can probably view it from the outside access panel (Atwood furnaces usually have those).

sound like a possible broken fan blade.
Sounds like a piece of debris sucked in there, and has moved it's position. If it has gone, and seems to work fine, I'd probably let it be. I once had a small piece of aluminum tape from some ductwork get in a fan, made a clicking sound, pretty easy to remove.RVRAC said:

My Suburban furnace started making noise last night. A constant short-tapping sound that reminded a little of when as kids we'd put baseball cards on our bicycle spokes (if you're under 50, ignore that). Got the electric heaters out and wondered who I could get to come out to our full-time 5er if I couldn't fix it.
Opened the access panel and the noise was definitely coming from the blower/fan. I thought "How the heck do I get to THAT?" as it didn't look easy. So I did what I always do: I stared at it trying to figure out what to do next.....and VOILA! The noise stopped.
I'm crediting my Superpower Stare....but as Gizmo said, either I'll never hear it again, or it will start up at 3 a.m.
Thanks to all who posted as your comments encouraged me to open it up instead of calling a mobile RV tech....and MERRY CHRISTMAS!
