Name of HVAC Parts

[Gary L. Porter]

What is the name of the round part and the part next to it on the right.

[David P. Valley]

Not sure...But let me take a stab at it before the answer is revealed...

A Plenum thermostat?

It's got to have something to do with the high/low settings.

They look like a blower thermostat and a high limit switch.

It is a Klixon temperature switch/control that can be normally open, normally closed or a combination of both depending on the application commonly used on furnaces as a limit switch. The oval shaped item next to the round Klixon should be the fusiable link.

Would this keep the unit from coming on? I already replaced the circuit board and the transformer. That is what del air said was wrong. They wanted 300.00 for the parts. I got them for 150.00 . But I saw smoke come from the limit switch when the unit died. I told him that but he ignored me.

Yes the limit has to be in the normally closed position to make the circuit if it burns up and or opens the circuit it will not run as it is a safety control.

Why should he listen to you if he can sell you $150.00 worth of parts rather than a $10.00 limit switch. You have already exceeded the cost of a service call???????

Gary,

You tried to save yourself money and do it yourself and look what happens.

You're better off leaving these things to the Pro's. I know it's tempting to Do-It-Yourself, but it always costs more money when your performing guesswork.

[Gary L. Porter]

I have not done anything wrong. He missed the other part. I replaced the other's. The reason I replaced the others was because it would take him 2 days to get the parts. Then they never called back.

Ohhh...OK.

Either way, I always take on DIY projects all the time, but (at times) I find myself bringing my unfinished work to a PRO and paying more out of pocket money than if I had brought the work to a PRO in the first place. It pisses me off at times.
