Furnace blower noise

My propane furnace blower motor is so loud in my OFF-ROAD POPUP we don't use it much anymore. It is my absolute final PLAN B keeping warm hehe... It will wake me up in the middle of night when it kicks in... Then when we do use it is way TOO MUCH HEAT for our small footprint trailer. Very hard to regulate the heat from it.

I have described the noise like siting in the back roll seats of a MD80 Jet Plane listening to the loud GRRRRRRR Noise of the jet engine which is probably just inches away from your head.

I have never heard a screeching noise coming from my Blower however...

I had a $500 dishwasher and they want $400 for new racks. They had a $900 dishwaher on sale for $500. Gee what should I do.

So true..... things are just being made cheaper and cheaper. Most standard appliances over 5 years old aren't worth repairing or attempting to repair. RV appliances are definitely included in this. I suppose an RV furnace is a costly enough item that it may be worth looking in to.

I do home inspections for work and it's amazing to see how quickly things are failing. Garbage disposals, dishwashers, water heaters, faucets and similar items in cheap track houses routinely fail before 10 years. There is still some decent quality out there but it costs you. Unfortunately, the quality of components in RVs is at or below the cheapest houses. I'm constantly amazed at the junk in my 2013 TT.

I suppose this is the reason I was so surprised at how little it cost :)

Our 2010 Keystone hideout does the exact same thing. It seems to happen at start up and as it's about to shut off. I stuck my fingers in the louvers and touched the cover and it went away. It seemed to have to do with the cover. Haven't really been using the heater much so not sure if it still happens. I think I tried tightening the four screws on the cover of the furnace. This is a terrible and annoying noise hope it helps!

My experience with furnaces is that they are all NOISY, even if there is nothing wrong with them. The furnace coming on in the middle of the night has woken me up many times.

Motors use sleeved bushing..no bearings
Screeching noise:
could be worn bushing,
could be dirty wheel(s) throwing them out of balance,
could be loose blower wheel(s) (either room air and/or combustion wheel),
could even be a bad main burner assembly (can screech due to disrupted gas flow thru assembly)

Need to pull furnace and inspect

I have worked on many furnaces in my day and I have yet to see one with bearings you can lube. many have tried but they will not last very long. you have to replace the entire motor and they are not cheap believe me.

they may use the same but I do not know off the top of my head what you have in your rig.
I am old and can just remember what I own
