SOURCE: honeywell round mercury thermostat - heat not coming on

If you tip the mercury switch so that it makes contact and the furnace doesn't start, it isn't the t-stat. Check the connections, then start checking the furnace.
In any case, ditch the mercury t-stat (recycle it properly) and get a new programmable one if at all posible. It will pay for itself many times over by turning your heat down in the middle of the night and back up by morning.

SOURCE: Replace three wire thermostat with four wire thermostat

From the two red and two black wires (and the specs in the pdf), your new thermostat sounds like it's designed to directly control the line voltage (120 or 240) to the heater. That's the usual way baseboard heaters are controlled.

Could your wires be red, black, and (old, yellowed) white, the standard colors in a 3-wire power cable? Just the red and black should be enough to control a 120-volt heater so I don't understand what the white would have been used for. If it were my heater I'd take off the cover(s) -- with the power off, of course -- and find out what those wires actually connect to.

I have a Honeywell RTH6580WF Wi-Fi Thermostat that has "Cool On" or "Heat On" flashing in an endless loop. Could there be a major issue?

Pull the power red wire off the thermostat and batteries out if it has battery backup, then reinstall...much like a computer restart. If this doesn't work, then replace your thermostat.

Manual foe a RCH9300WF

It's pretty basic actually. I've done this with Nest and Honeywell Lyric. The only thing you need to do is removing the current thermostat from the wall and connect the new one.

Set it up using your mobile application and you're good to go.

Is there also an on/off switch for the fan on the furnace itself? If so check it make sure its set to on. Also check the on/off contacts of the switch on the t/stat to make sure its working.
