Hello,
So I have an Atwood 8535 in a 2001 Four Winds 38’ Toy Hauler.
It’s been working fine for a month or so. It recently had a new motherboard put in by old owner.
I put a new igniter electrode In it when I got it. It’s been working fine ever sense.
On start up the blower motor would squeal. I sprayed the center wheel arbor with penetrating lubricant and it quieted up.
Most recently it was running but kept going out. I thought the tank was out so I switched it to the other full tank. It was still lighting for a few seconds and going out. Then trying again. It was constantly doing this, more than 3 times and a lock out, until eventually it would catch and stay lit.
But even while lit, it’s BARELY warming the camper up. It’s usually very quick. The air flow from the vents are low. There’s warm air coming from them but it’s usually hot. Too hot to stand on while it’s going.
What does this sound like to you?
The constant on and off made me think of flame sensor. But the low flow makes me think the blower motor is on its way out. I sprayed the blower again because it felt like there was some resistance when I spun it by hand. But if the blower wasn’t strong enough, wouldn’t that cause an over heating problem? It’s been running for an hour now.
If this is a blower problem then fine, I’ll replace it. But the constant on and off until it stayed lit made me think of another problem.
Any thoughts?
Thanks
