Furnace not staying on until target temp is reached

Hi!

Nest was professionally installed and no error codes.  Temp is set to 69F and a thermometer shows internal temp at 58.5F.  The furnace comes on occasionally but does not stay on as expected until the house reaches 69F.

It’s in Heat mode not in Eco mode because the OnTech appointment took a while to schedule and it has been cold in the house for a few weeks now.  The unit is charged and I can connect to it via WiFi on my iOS devices, and the “Time to Heat” is noted as 1 hr 25 min, but it’s pretty much staying there…it’s 47F outside.  I also just changed the filters.

Any help would be appreciated, thank you.

My problem was in the furnace as well…I had an HVAC specialist take it further apart and some of the interior wiring was quite melted/corroded.

Having same issue here. Ensured Seasonal Savings is off.  Schedule set to 67, home temp is 57. Eco temp is set to 65, though is in Heat mode. Adjust temp to 75, nothing happens.

Update:

Called out professionals and they found two birds.  One was all the way to the fan blades while the other was stuck in the exhaust tube.  Cleared everything and the system was back to normal.
