I would think it safe. However, running it too long without service it may let you down in a cold snap, or other issues like corrosion or water into an expencive board could result.
A question is this a 2 speed heating unit? If so the second switch may not come on until the board is told more heat needed. On gas furnaces that have 2 or variable speed heating there is usually a w2 connection required. Yours may or may not have this function.

Sounds like you need a new wire. Maybe rust has damaged all conductors? Water in the insulation creating resistance?? Run the new wire and go from there.

Is that a NEW thermostat? If so, not all thermostats are created equal. Some are made for gas, some for electric and some are for heat pump but ALL are different. Ones set up for electric don't have switching for electric gas valves and ones for electric and gas don't have switching for the aux. 10 Kw heat strip in a heat pump. Thermostat wiring color codes are also different. If you accidentally got a "stat" for a heat pump, the color markings for the wiring inside it may be the same but could connect to something completely different in your gas heater. Good luck.

Sounds like the capacitor. It’s a shut down error because the outside unit is running slow. The capacitor is 415v 6uf. Would suggest a qualified person install it. It’s a cheap part.
