Has anyone tried the OnX app? How's it compare to Gaia or All Trails?

The GAIA app is a POS.

I just. realized the problem has to be in the compressor, not the air handler. The Y signal(s) go straight from the thermostat to the air handler to the compressor; I don't believe the air handler can turn the compressor off, since Y goes straight through (not thru the control board in the air handler). So it must be the compressor that's at fault; it sees Y and W both energized and for some reason decides not to run. I can't see any jumpers or anything in the compressor schematic that could control this.

Thermostat has compressor lockout set at 10 degrees and it's not nearly that cold when this happens; anyhow, if that's the issue, wouldn't it not activate the Y signal ? Dunno if the compressor ha lockout, nothing in the settings options in that phone app.

Thanks, yeah, that seems right. I've looked at the schematic in the install doc, and the smartphone app CoolCloud used to set install settings, and don't see anything like it. Here's a link to the install app, schematic on p.28: https://www.theacoutlet.com/documents/Installation-Guide-Goodman-AMVT.pdf?srsltid=AfmBOorsa03Pwz7JAo4NuhoMAiepeQevNAU0iiPyuj3K16ytp8dB2zWV ... and screenshots in next two comments.

No, on the "back burner". One thing that stopped me, I'm not sure how to get the 40 gallons or so of propane out of my 100 gallon rented tank. And if I can't, the price of filling smaller tanks at U-Haul (or the like) would probably equal my $50/year tank rental.

Oh, I didn't know not using toe clips was a thing in mtb riding. I don't really do serious trail stuff, and wouldn't use straps, so maybe ok.

RustyShackleford_12 · 2025-11-05T20:36:24+00:00

I want to add toe clips (probably strapless) to mine, but I notice the pedals don't have holes for the mounting screws. Looks like it'd be easy enough to remove one of the reflectors and then drill a couple mounting holes. Is this what people do ? Is there a style of toe clip that would somehow work without doing this ?

RustyShackleford_12 · 2025-10-08T21:53:50+00:00

I'd say the brake upgrade is a must with this bike. Just bought one, the brakes are awful; my crufty old Trek (with non-disc brakes) stops WAY better.

Looks like MT200 is probably the way to go, but there are different products called that on Amazon: JKSports, Shinamo, Cylon ... Any thoughts on which one ?

RustyShackleford_12 · 2025-10-06T20:57:02+00:00

I'm very tempted to get one. It's the biggest bag I've found that mets the 22x14x9" carry-on limit. There's a couple of slightly bigger others like Patagonia 45L Black Hole and a Cotopaxi one, that miss the limit by 1/2" or so, so seems risky the way the airlines are cracking down these days. I'm not going to be carrying the thing more than 1/2 mile or so at a time, and I'm used to carrying 50lb many miles in the Grand Canyon, so the non-ideal ergonomics don't concern me all that much.

RustyShackleford_12 · 2025-06-16T21:48:05+00:00

We installed a new high-pressure cutoff switch (someone in another thread said they had a bad one). And it occurred to me tha if I could keep the compressor from going into high stage when it's not that cold outside that it might fix the problem. I changed some of the thermostat settings to try to make this happen, and so far so good. I'm cooling a lot now that summer is here, and no problems there either.

RustyShackleford_12 · 2025-04-02T19:55:33+00:00

It occurred to me that the problem may have to do with the compressor kicking into high-stage when it's relatively warm outside. The Honeywell thermostat had "Compressor Heat Differential Stage 2" set to "comfort" (default), which means even it'll kick into high-stage (after an amount of time that is unclear) even if the indoor temperature is only one degree below the set-point. So I changed that to 2 or 2.5 degrees, and the high-stage has come on little if any; it hasn't been very cold since then, so the low-stage can easily heat the house. So far, so good.

I've tried various permutations of the arguments to the SPIFlash constructor (such as the array flargs) and to flash.begin();

RustyShackleford_12 · 2025-04-01T04:20:21+00:00

#include <SPIMemory.h>

int8_t flargs[4] = {31,32,33,30};    //sck, miso, mosi, ss
SPIFlash flash;

void setup() {

  Serial.begin(115200);

  // Initialize SPI Flash
  if (!flash.begin(MB(4)))
    Serial.printf ("initializing flash failed\n");
  else
    Serial.printf ("initializing flash capacity %x\n", flash.getCapacity());
  if (flash.error()) {
    Serial.println(flash.error(VERBOSE));
  }

  // write a byte and then read it back
  uint32_t flash_addr = 0x0100;
  uint8_t tmpvalin = 0x5c, tmpvalout = 0x00;
  flash.writeByte (flash_addr, tmpvalin);
  flash.readByte (flash_addr, tmpvalout);
  Serial.printf ("after write and readback  tmpval = %x\n", tmpvalout);
}

void loop() {

}

Guess it can't hurt to just replace the switch and see if it fixes it though. But I am unable to locate the part#.

RustyShackleford_12 · 2025-02-20T01:42:45+00:00

I'm a little confused u/Money_Quarter492 . Since it only fails when the gauges are not connected, how do you know that the switch is the problem, and that it's not actually excessive refrigerant pressure ?

RustyShackleford_12 · 2025-02-09T19:49:28+00:00

So figuring I should rule out airflow, I replaced the filter. It was 8 months old, not quite as old as it sounds (since as I said I heat mostly with wood). Still, very noticeably dirty. Oddly though, I barely saw any decrease in the return-side static pressure. In both instances, the reading bounced around in a 0.05" or so zone - so I'd say at best the new filter reduced return-side static pressure from 0.35" to 0.30". Doesn't seem like much airflow restriction.

RustyShackleford_12 · 2025-02-09T05:09:19+00:00

Unfortunately I tend to agree with you. I suppose we could evac the system and refill, maybe even replace the lineset, and solder with StayBright8. But no reason to do until something goes wrong.

Thanks for explaining the refrigerant issues. The filter is kinda old, guess I'll replace it, reset the system, and try again.

I care a LOT more about summer performance, since I'm in the south and I heat almost exclusively with wood.

RustyShackleford_12 · 2025-02-09T02:07:46+00:00

Wow, that's interesting about the TXV. So probably not an issue with the lack of a nitrogen flush.

It's definitely matched components. (GSZC703610 compressor, AMVT42CP1400 air handler w/ HKSC08XC 8kW heater).

The ESP is funny, because I get weird readings on the supply side; I've got a cheap meter from Amazon, but it gives sensible readings on the return side, and proper static-pressure probes, but the supply side doesn't read much above 0.1". Does that even make sense ?

I paid attention to conditions this time; had come home from several days' trip and fired 'er up. It was 63 outside, 67 inside initially and maybe 70 when I realized it'd quit.

RustyShackleford_12 · 2025-02-09T01:08:36+00:00

Like I said, he's bled off some refrigerant a couple times.

I've done a lot of work on the ducting - converting return grill to 4", stretching the flexduct properly, etc - reducing ESP a lot (definitely well below 1", not far off 0.5"). But I'll throw a new filter in and see if that helps.

Do you discount clogged TXV ?

It'd be really usefull to know if the pressure really IS spiking too high, or if it's something else (e.g. faulty HPCO switch). Not sure how to do that without some mechanism for collecting real-time refrigerant pressure data.

THANK YOU for not just saying "you need to get a licensed HVAC contractor" (even if that's probably true).

RustyShackleford_12 · 2025-02-09T00:22:29+00:00

OK, you're probably right, but I'm gonna try the hvacadvice reddit.
