Wow. That is some hardware there in the x-ray.

Or, you can let them run. Most of the units I see do not turn off the heaters when the compressors run. I see maybe 5% that turn them off.

Does this sideways number five show on the outside of the sealed box?

The thing that will help you get a job someplace else is fully understanding the big picture of how systems work and how to properly diagnose them. Those principles will essentially be the same...

Yes. Aux contacts (which are specific to the brand of contactor for reliable fit) should be replaced when the contactors are replaced.

Good morning, everyone!

If there is an interruption of voltage into the safety chain., you will still read zero volts across the switch.

So...

You need to confirm both sides of the switch to common, reading full...

Ask your doc, "if you needed this, who would you have do it, and where?"

Bypassing the rollout or limit is not as good a diagnostic as measuring the voltage at the terminals.

Let's not post in threads from September, unless you are the OP providing an update. Thanks.

Yes.

Don't tale this the wrong way. We don't know anything about you.

If this was the Pro section, we could all jump in with our experiences.

For right now, the prudent response is to...

My money is on the rollout. You may need a wind baffle for the flue outlet...AFTER you check the HX.

I love happy endings.

Resideo purchased the designs, trademarks, and service marks, so that they can call these Honeywell thermostats when indeed the company selling them is not Honeywell anymore.

X2 on getting up for the free Pro membership status.

When you have 15 substantive posts in the open areas ( like this one) use the link in the bottom of my signature area that says, "how to become...

Good morning, everyone!

Am I correct in thinking that the limit is an aftermarket part?

Take care of yourself, then take care of your responsibilities. Serving others is good for you.

Well, I hope for a good outcome at the Doc, but really, the big C is not as dangerous as it once was. Today, we are enhancing our own cells to fight it. We will completely conquer it in my lifetime....

You need to make sure that you're meeting all of the board's input requirements before the board will reward you with lighting off the gas.

Are you smelling gas when it does not fire, or is it...

Good morning, everyone!

Ding ding ding.

Typically, in a forced air system, the stat is located away from other heat sources and the supply diffusers, and near the return air grille.

I have not had an oxy rig on my truck since the truck with that rig was stolen, but for me, it always depended on the tip being used. You can put a lot more pressure into a large rosebud, for...

Good morning, everyone!

Good morning, everyone!

For those who would like to join me this morning, we stream live at 9:00 am and 10:30 am EST, ...

In my work (which is strictly commercial) when I have a situation where a limit switch is tripped, I have to assume that I'm not the only company that visits this unit and I may not even be part of...

Good morning, everyone!

Magnet. That's what I was thinking.

If this seems a little disjointed to you, Alex, it is because this is an open forum. We are not going to provide steps in the open forums, because they get indexed by search engines.

Unless your...

Maybe it's just a difference in terminology, so I'll ask...

What are you referring to as a "power unit?" Can you post a link?

It is only the scroll itself that can spread apart to tolerate a little liquid.

Liquid is still just as bad for the bearing as it is in a recip.

I am wondering if both the indoor and outdoor units were replaced, and if someone actually had this working right from day one. Let us know what you find.

Ok...so the issue is that both return wires have power on them. Good to know.

Their purpose is to not allow the sump of the compressor to be the coldest place in the system. If that happens, liquid refrigerant pools there by condensation, and you can wash the oil out of the...

Good morning, everyone!

It was my understanding that the powers thought that an open area was necessary.

Indeed, the applicants need that first 15 posts, and this allows for that to happen.

This forum's higher traffic is not due to visibility. It is the incredible number of search engine referrals being sent to the forum, because it is searchable by search engines.

This is also the...

In this case, you get a qualified tech to take the pieces apart and do it right. There are techniques for making these corrections.

Ask three friends whom they have used in the past, and would use...

Allow me to add:

This is an open forum. That means there is no keeping out the search engine bots that are tasked with indexing the net. As a result, just any old searcher can read what we post in...

Good morning, everyone!



And like the song says,

Give thanks....with a grateful heart.

Yes...I know that is the limit.

How was it shorted...between which two circuits...or a circuit and ground?

Some companies require you to have your own tools, while others provide a vacuum pump, recovery machine, etc, while the tech provides the rest.

You would have to ask them to do it by clicking on the black triangle in the bottom of your post....where a window will open and you can type in your request.

On the contrary.

When I think of commercial, I think of easily understood systems that residential contractors do not understand and have no experience working on. I will spend perhaps one day a...

A great guy who did great work to support our troops on deployment. We miss you, man.

We have a sub forum for used stuff and old new stock called the Junkyard.

The mods can move this post to that forum is you ask them.

HTH.

Good morning, everyone!

Indeed.

Checking the board connections can reveal the lack of 24 volts caused by the legacy SD break.
