Popping Noise

[canula2]

Feeling inept having 2 post twice in 2 days, but there are constant popping noises. I have just noticed this since we have had 2 use the heat the last 2 trips. Is this normal? Being a light sleeper it is driving me nuts. Sounds like the first strike when cutting wood. It seems ti get worse when the heat is getting ready to come on, lasts through the whole heat cycle. Something still pops even when heat is off. Is this normal for RV heating. While I realize it is not home, my other fifth wheels did not have this constant popping noise. If it helps I have a 351SKTS. Thanks in advance

Could it just be furnace metal expanding and contracting from the heating and cooling?

[canula2]

That was my thought. If thats it then it sure is loud

Is the popping sound kind of metallic, like you could make by striking a sheet of metal with your hand or fingers, or is it something sharper and more like a miniature fire cracker ? If the former, I would suspect expanding/contracting ductwork. If the latter, it might be something electrical, and should be pinpointed and investigated asap. JMHO

It is more a striking pop, I do not believe it is electrical. I am sure it is just the ductwork expanding and contracting, but boy is it annoying this light sleeper. Thanks for the response

I have a 2012 351 RLTS. We use the fire place during the day to keep the chill off, but when the furnace kicks on we get the clicking noise from the igniter for the furnace and some vent popping, but nothing like you described. Check for stuff inthe duct work. I had to take a small shop vac hose and run through the heat vents for construction debri.

Was having the same issue with ours, it happen on heat up and then cool down.
Tried everything I could think of and this one day I was in the basement and figured it out. The heat duct that runs to the front is held in with screws on each side with flat washers. I tightened them all the way down and then backed them out until the noise stopped. Hope this helps you with your issue.
