sailswitch location

[scottsnider]

I have a 2004 HiLo trailer and my heater is not working, blows air but no heat, worked good last year but not now. what I am looking for is PICTURES of where to look for the sailswitch. I have tried YouTube and they tell how to fix it but not where its as to even see it. If I can see where it is I can decide to either do myself or get a pro. I believe its a suburban and its a small trailer only 22 ft s the heater is not large. I hope someone can help me with PICTURES.
Thank you, this webpage has always been helpful in the past I hope you guys can come through again for me.

And check the unit for the blinking light, this is a code telling you whats wrong. I belive your furnace has this.

Just note last time someone had thos problem on the pop up site, the reset switch was bad. So you can also check that to see if the power is getting through. But if the fan is working, it probably is getting power. There is also a limit switch on these also. So , if its not the sail switch it could be the limit switch. Not sure if the fan would work if it trips or not. Usally its a sail switch. While you have it apart, good idea to clean the flue and make sure there are no obstructions in the vent pipe.

Regardless, you have to pull the furnace to do a thorough check of the limit and sail switch. The fan will run regardless of a Bad Sail or Limit switch. His older model does NOT have a fan shut down when there is a failure to ignite. It is always a good idea to replace the Limit switch on an older Furnace, when repairing the furnace. Doug

If you watch the vid I posted , you need to remove the unit, and the switch is on the bottom right hand side of the unit.

Not my vid, also, try the reset switch on the unit.

Check the fan, I've seen them get so much dirt on the blades that it couldn't move much air.

Use the below link to post a pic. Copy the code it generates and paste it in your post as written.

Thank you all for your comments, I checked today and its an Atwood Furnace and I took some pics to but I have never been able to get them to work on this page, in fact I have tried to add them here and nothing it just will not click an post, but that is another issue. Atwood 7916-11

Mine is mounted out front next to the blower motor so the wind from the vanes activates the switch. I recently replaced the time delay relay, a four wire relay mounted on the end of the blower motor, to fix my unit. It was not letting the power get to the electronic board that signals the burner to ignite. This is an older Suburban SF 35 unit so the technology might be more advanced than mine.

Some of the heaters have a light that flashes a code, telling you whats wrong with it. Look for that also.
