Take the cover off the burner compartment of the furnace.


Observe the sequence of events which occurs when you turn the thermostat up to, oh, 85 degrees. Report that sequence in order and in detail here.

In particular, do the burners remain on constantly, or do they cycle on and off periodically, and what happens to the operation of the fan circulating air around the house?

Here is a link to some info that may be of benefit to you:

You stated there is a steady light red light with no codes. I suggest you watch the control board and see if you can observe a code when the furnace decides to shut down. It sounds like the furnace is shutting down on a high limit switch tripping. This is normally caused by lack of air flow. I suggest you make sure the condensate trap is clear and drain line is flowing properly. Also make sure the tubes coming from the inducer motor and to the collector box are clear.

A lot of times with that particular series of furnace the drain tubes were never configured properly. That can cause problems such as yours. Figure 10 in the manual I linked shows the proper hose configuration. If the installer did not route the hoses properly and the plugs not put in the right place it causes problems such as yours to manifest sometimes not until years later. There should be a label that shows proper routing of the hoses on one of the furnace panels. The configuration of the hoses is dependent if the unit is installed vertically and horizontally. I would verify the hoses are routed properly and plugged at the proper location. Did you insure the condensate drain hose at the bottom is completely clear. Here is a link to a recent thread that had a vexing problem with a Carrier furnace with a similar setup and how it was finally resolved:
