But I saw smoke come from the limit switch when the unit died. I told him that but he ignored me.

What were you doing sitting there watching it die?! :-0

I have never seen a fuse link and a Limit switch in series like that (unless it is a roll out sensor) some where down the line. I think that is a fan controller with high limit. Is that a Carrier/Bryant/BDP? I see a lot of yellow wire in there?

Take the part out and bring it with you. You will need all the data from it. It may have to be ordered threw the equip mfg as it does not look generic.

Gary if you have a volt ohm meter you can test the klixon switch and the fused link.Just take a reading across the terminals.If you get a reading its not the controls.If you do not get a reading change the parts.Matt

If it is a fan controller, it will be normally open.

I suspect that there is something else going on.
Need someone that really knows what they are doing in there.

Hey guys I am sitting with my feet up in hotell room in Denver Made that long trip today. Class tomorrow on the B-Cam

I cut you short yesterday was trying to pack

The Klixon that was in the pic looks as if it is on the furnace am I right and what are you doing running your own furnace in A/C weather.The fan switch and limit are totally different from the fan switch or power source from the board which would operate the blower in he cooling mode.

you have me totally confused can you explain this in detail as to what mode you are concerned with.

[Matt Berman]

David is correct if it is a fan control there will be no reading across the terminals,i assumed it was a limit. Assumption is the mother of all screw ups.There is probably something else going on in the system.Save time & money ,call a local pro.Matt
