Hi Craig, The top switch is a fan Switch. The bottom is a lower limit switch. Fan Switch # 7975 - 3281 can be seen and ordered here by paging down : http://www.aberdeenhomerepair.com/store/product/2412/F110-20F--fan-switch-7975-3281 IF you need or wish to get the lower limit, after adding fan switch...

Hi Craig,

What is the complete furnace model number ? Is the limit that is tripping up next to or attached to the blower housing ?


Or is it about midway of the furnace ?




Thanks,
Robert

Hi Zac,

Go to transformer and test Primary-Line side for 240vac across the two terminals.


Then go to other side, Secondary-Load side and test for 24vac.



Let me know what you get.



Thanks,
Robert

You're very welcome, happy to help.



Thanks,
Robert

HI, What I was saying is that the ignitor could have been going bad earlier, but the inducer motor problem/pressure switch problem would override it and diagnostic light would show that first. Once you corrected that and got it going again, the ignitor problem surfaced on diagnostic light. IF it get...

Hi,

The t-stat itself will often cause problems. Great ceiling fans, but not t-stats.


The sequencer test itself was all that was needed.

Hi,

Do you still need any help with this ?


Thanks,

Hi, Your furnace has two contactors and two relays that together control the elements and the blower motor . The circuits can run through them even though that one may not actually control the circuit or component. Without thorough electrical testing, hard to say which one may be at fault or if it's...

Hi, Sequencer is definitely bad. Sequencer # 3115 - 3571 can be seen and ordered from here by paging down: http://www.aberdeenhomerepair.com/store/product/2311/3115-3571-sequencer I would suggest replacing the Hunter t-stat with a Honeywell. IF you choose to remain with the Hunter, leave it set to H...

Hi, Not sure which pressure switch you received, but the replacement switch does have a different p/n, but also has the two vacuum ports. Sorry for the wrong part and misinformation. For the ignitor, there is often more than one problem that arise at same time, sometimes tied together. In this case,...

Hi,

Could be several things. Need to check for voltage at blower motor and elements to find out exactly where the interruption in power is at.

Robert
