I appreciate all the reassuring responses.

Thanks, again!

I inadvertently used my r22 gauges on a 410a system. Is there a danger of mixing oils? In other words, have I mixed the r22 oil that was left in my hoses with the oil in 410a system? And, could that...

Thank you!

Can anyone tell me where to find a schematic for a Bohn/Heatcraft model bht032x6c?

The Cooper-Atkins model DPP400W-0-8 works fine on my daughter's Waterfurnace. It has a small tip that can...

Thanks, guys!

I tried to charge a Napoleon mini-split yesterday and found that my hose would not fit the service valve. What size is it and is there an adapter I can use?

Thanks!

Where do I find the nameplate on a Waterfurnace Envision model number NSH060A111NEL? I need to know how much r410a to weigh in.

Thanks, rundawg!

Can anyone hook me up with a wiring diagram for a Bryant heat pump, model 633ajx024-b?

Thanks, coolwhip!

Can anyone tell me the capacity of the furnace in a Carrier 48TFE008 roof top unit? The nameplate has been covered up with the disconnect box.

Thanks for all the helpful replies, Guys! I think I'll just let the board of trustees decide what to do about the cooler.

If I put in a new compressor, drier and cap tube, can I put in r134a in place of the original r12 and get the same performance?

I had the amp clamp around the start cap wire when I it read 1.2 amps. I didn't think to clamp around the common wire. I'll do that. I checked the start cap MFD. It read out 207 MFD's which was...

I'm pulling 1.2 amps for a few seconds, then the overload trips. The overload resets and the same process starts over. Funny thing, though, is that I'm not hearing a hum. I've ohmed out the...

I'll do that when I can remember. I keep forgetting.

It does have a current relay.

I'm sure it's older than 5 years. Is the age of the unit printed on the nameplate?

I did check the start relay by putting a voltmeter on the proper terminals and setting the meter on min/max. It...

No, I cleaned the condenser weeks before it quit.

I'll make sure it only drops out after it starts.

Thanks! I'll give that a try.

My church has a True GDM-12 soda cooler that has quit working. The compressor will click as if it's going to start, and then, almost immediately it will click again and fail to start. I checked the...

How do y'all select a start relay replacement. The ones I have looked at are rated by volts and pickup minimum and maximum. The one I took out is marked with the Carrier part number, nothing about...

The noise I hear is like the rattling noise you get when you're adding refrigerant as a liquid.

I'll check those measurements tomorrow and get back to you.

Superheat was 2 degrees.

I should have mentioned the superheat. It was 2 degrees. That's why I hesitated to add any refrigerant.

Yes, TXV on indoor coil

I'm dealing with a Bryant heat pump, model 633ajx060-b. The problem is that I'm only getting a 10 degree temp drop across the indoor coil. It's a 410a system. My pressures were 245/160 at a 70 degree...

I should have been clearer. This tank would be used only for scrap refrigerant.

Could a used propane grill cylinder be modified to use as a refrigerant recovery cylinder?

The leak is in the coil. I always heard that the copper was too thin to braze.

It's R410A.

Year of the outdoor unit is 2002. It's a 12 SEER.

My church has a heat pump system with a leaking outdoor unit. I'm a former HVAC service tech who has been retired for several years. I would like to replace the unit for the church but I don't know...

I'm just posting in order to find this thread again.

Thanks, Sky! I agree with you. I see nothing wrong with that practice. I believe the bulk of the responsibility should be on the contractor.

Can anyone explain to me the term "bought down the warranty"?

What does that mean? The installer "buys down" the manufacturers warranty? How does that work?

I own a Kenmore model 2539668421 refrigerator. It seems to go into defrost mode much more often than it would need to. What determines when it goes into defrost? Time, temp or both? Does anyone have...

I just realized that I have 14 posts here. So I'm going to take RoBoTeq's advice and let him know how much I admire him and that he's my idol and that is the biggest reason I would like to be...

I agree with Mark.

When I was in trade school I heard a lot of bad things about Goodman. It was referred to as Junktrol.

But when I got out in the field I found that Goodman equipment had...

Thanks, udarrell, for a helpful tip.

I run into the same problem around here.

I'm retired but work during the busy season for my old boss doing PM's. When I come up against this I'm stuck between a rock and a hard place.

On the...

My brother's church is considering replacing the 25 year old air handler, Ruud model uhqa 1220 t. The heat pump is an Arcoaire, model yj036gb1 only 9 years old. It's a mismatched system that requires...

That's an EZ Trap. It has a float switch installed and wired to shut the system down in case the drain backs up. The red dial looking thing is a cap that can be removed to use the brush that comes...

That's it. I just hope I can find it again next time on my own.

Thanks, guys!

I feel like an idiot. I just looked at "tips and tricks" yesterday and found it quite informative and very entertaining. Today I can't find it. Can someone direct me to it?
