Re: Furnace troubles
So, today I blasted all the gas lines out and pulled the burner unit to see how the flame sensor/ignitor was aligned. I adjusted the gaps as specified in the manual, then also tweaked the flame sensor closer to the flame and the ignitor closer. I then retested the gas pressure with my manometer and checked for leaks with the manometer. I turned on the furnace waited for its various start up cycles and it fired up and operated perfectly. I let it run for 15 min and it operated flawlessly. Thanks for all of your comments and suggestions. I imagine the only real problem I had was a ignitor/sensor alinment problem. I am glad that I removed the furnace and preformed the maintenance that I'm sure the unit needed anyways...529Views0likes0CommentsRe: Furnace troubles
The one thing I have not tested is the actual Gas pressure at the furnace. I tested the gas pressure at the stovery due to the ease of hooking a manometer to it. I need to purchase a fitting to test it at the furnace. Unfortunately, the nearest store is quite a drive.529Views0likes0CommentsRe: Furnace troubles
I did, and read thru it. I am just seeking and advice I can from people who have been there done that. I will adjust the flame sensor/ignitor assembly as shown in the manual and make sure the flame sensor is completely engulfed in flame. I know all the wiring is good and all contacts have been cleaned and tested for continuity.529Views0likes0CommentsRe: Furnace troubles
So, from my reading and forum suggestions, I will blow out my propane lines/plumbing and adjust the ignitor/flame sensor today. Maybe I ought to tweak the ignitor and flame sensor close to the burner as well. What I have learned is that these explosions can be caused by excess propane build up or a lean gas mixture (clog in line, low pressure). Also I have read that a dirty burner can cause this, but I have already cleaned it out and when it did light the entire burner was lit evenly. If anyone else has any knowledge of furnaces please let me know other potential areas to investigate.529Views0likes0CommentsFurnace troubles
Hello there, my first post... so I have an old 5th wheel trailer I have been fixing up, a '84 alpenlite 28'. So, I tried to get my furnace running, first of all it was missing a ignitor/flame sensor-so I got one an installed it. So when I tried to fire it up it would light for a few seconds then go out. So I figured the flame sensor was not sensing flame. I figured the whole darn thing needed a cleaning and inspection, so I removed it and cleaned up contacts, tested the sail switch & high limit switch, blew out the burner area, cleaned the gas tube & orifice, and tested the soliniod/gas valve. Everything tested good. So next I tested my actual gas pressure and it was low, so I got a new regulator and retested. I now have 11 inches of water ccolumn with other devices running. So I tried to fire up the furnace again and after all the air bled out of the line it fired up and ran fine for a few min then the flame went out. So I turned the thermostat off and on again and it fired up for a few seconds then the flame popped loudly a few times and wouldn't relight. I did this a few different times until it popped really loud and blew a chunk of my flame sensor gasket out. It is a atwood/hydroflame model 82. What could cause this? Flame sensor/ignitor alignment? It is brand new... circuit board issues?(it's the only thing I can't test) Soooo, now I come to the experts for advice!1.9KViews0likes12Comments
