I'm not sure how some of the newer Amana's are but the few I service at the hotels are junk. More issues with them then any other brand.

I know it's not apples to apples since most are PTACs but we purchased some new amana PTACs and the first one I put in failed in a few weeks. Haven't put the rest in as we are keeping them as spares. But based on history I don't have high hope for the rest

Story and 1/2. I agree, 80K to me makes more sense.

This old ArcoAire setup has been a blessing. One ignitor, one new brain box, three vacuum induction motors (I bought a junk one as the second, lesson learned) over some 28 years.

If you go too big with your ac you will have mold problems. It needs to run to dry the air out.

If you're sweating your walls I can see that..that's generally an insulation issue as well...I try and keep humidity under 40% at my place that drys some people out lol

 

[NC-smokinlmm]

It’s probably exaggerated in the south. It’s humid down here. Lol

An oversized system can be designed with a reheat coil to facilitate dehumidification without freezing you out. My indoor pool units are like this as well as the building unit for one of my hotels

Well apparently they sprayed too many chemicals this week, bad weather all night. Had a tornado warning / shelter while I was at work last night until 10pm or so (one spotted in Centerburg). Then on my way home the road into town was closed off because it looks like one hit our town. We live a couple miles south so we were OK

Brother was inquiring about Dad's old 8mm projector, as he has all the old reels and wants to try to show old films when we're all together next month for Dad's party. I have it, so dug the old Bell and Howell out of the attic to inspect it. Looks like I have to replace the power cord on it, which is turning out to be lots of very interesting '60s technology fun.

This unit is all cast aluminum, and actually kinda intuitive to take apart. Really neat. There's 60yr old dust and gunk in this thing.

Looked online and found a replacement bulb and drive belt, which seems to be the only two parts even available for this.

News says we had 3 confirmed touch downs.

wtf man. This is getting old.

7 days in Tom figured out a title

3phase motors don't normally have thermal breakers in them but possible. 140° is not much. So maybe the VFD shut it down. What is your pulley ratio?

3rd light is to indicate what control is active. Remote or front panel. 5th light is is to indicate the display is showing Hz.

Make sure to set in the programming F0-00 to 1 for fan mode instead of constant torque mode.

Also you can adjust F0-10 for maximum frequency so you are not limited to the default 50Hz. Maybe try 120Hz to start with. May need to adjust F0-12 to match

F0-15 might help with motor heating but is normally only used for noise

You can play around woth F0-17 and F0-18 for acceleration and deceleration times. I'd start with 5 seconds and adjust from there. Too quick of decel can sometimes pop codes. Somewhere there might be a setting to coast down. I normally use that if available (F6-10 to 1)

Make sure F1-01 matches your motor kw or more if you want to overdrive the motor power. Some motors have a service factor of 1.15% or 1.25% of the nominal rating


F1-02 should match the motor voltage rating. Likely 208v

F1-03 should match the motor amp rating. Adjust up for service factor

F1-04 put 60hz here if not already

F1-37 you might want to try out #12 and take the belt off during tuning

I think I got most of these done. Didn't mess with F1-37 yet.IDK how, just played with buttons
IDK if it's programming, once I hit stop, and run light goes out, only way to get it back on is to power off then power back on

Edit
I can run a double pole light switch to have an on/off by the VFD. Basically run a line down each side of the switch right?

Will the motor restart if, without cycling power, press the reset button and try starting it again?

I push the stop/rst button to turn it off the "run indicator" goes off, both LEDs screens stay on, top one flashes, push greet start button either with quick 1s hold or prolonged hold nothing happens until I cycle the power

 

[2004LB7]

Try pushing the stop/reset again before the start. I'm trying to see if there is an error or if it is a programming issue. An error should reset and restore normal operation. Programming will not

Google what Melinda said about it all a few weeks ago. Seems we aren’t crazy to think something is going on.

So, had it running, hit stop/rst button. Everything stops top LED number pad flashes, run indicator shuts off.
Held green/run for 5s nothing, pushed stop/rst hold for 1s then push green/run nothing.
Only other ways to stop fan is run hz to zero or kill power.

Interesting.

I can only think of two possibilities.

One, the VFD is going in to error mode and not resetting or the control panel is not configured correctly so it receives the stop signal as an emergency stop situation

I'd check the F0-02 and make sure it's set to 0, and maybe check what F0-27 is set too.

What did you set F6-10 too? I suggest setting to 1. I've see this as a source of faults when coming to a stop and if deceleration is not set right. Easy to fix if you can just have it coast without any time restrictions

F0-02 was set to 1 reset to 0
F0-27 is all 0000
Set F6-10 to 1 forget is it was something else

Edit opt test works hit green after stop everything goes back to previous speed when stop button was pushed

Edit #2 VFD shut the fan of after 10 minutes

How many amps does the display say when running? Was the motor hot?

 

[malibu795]

Set amps at 6a
Just shut it down for the night had an ERR-009 or ERR-0009
Motor is warm been running it at ~30Hz or ~3amp
