I know!

The screen does have one small indicator, as I mentioned up in post #9:
The small word "heating" shows up on the screen when in heat mode.

I replaced the thermostat with a wifi model, a White-Rogers/Emerson Sensi, model 1F86U-42WF. My system is heat-only (boiler), that's two wires, plus I added a C wire although for the great majority...

I ordered the capacitor, swapped it in, reassembled, and the washer appears to be working just fine now. Replaced the coupler while I was in there, it is almost surely the original and the rubber was...

For WiFi thermostats I am also liking the White-Rodgers 1F86U-42WF (same as UP500W or Sensi), although it runs about $30 higher than the Honeywell RTH6580WF.

Thank you much. It is not actually working as an outdoor reset, just a temp sensor. I do have outdoor reset, the factory kit, that one I am sure of the hookup: it is wired directly to the boiler.

Thermostat recommendations and add C wire to Munchkin 140m boiler

Heat only setup, I need to change the thermostat. I like the Wi-fi option and don't need a touchscreen. Intend to use a Honeywell RTH6580WF. Anybody want to talk me out of that? I'm all ears ...

By the way, thanks for helping out.

The yellow indicator does not glow when I throw the breaker, nor when I disconnect the W wire.

It's a really simple setup: just two wires at the stat, they go to the boiler. Currently there is also one jumper at the stat. When the thermostat closes the circuit, the boiler fires up...

Great input from everyone, thank you.

In recent projects I needed to check both a diode and a capacitor, so I am more inclined to go with a DMM than analog.

Cheapest I can find the blower is $400. Out of Omaha, which is close to me. The control board costs right about the same!

Yes to NJ Trooper's last question: I see 194 or 195 (i.e. fan speed of 1950) on the display when the boiler cuts out and throws the F14.
