Honeywell RTH221 programmable thermostat for a gas wall mounted heater. Even though the thermostat says that the heat fan is running, the fan in the heater won't go. The pilot on the heater IS lit, and there is a little bit of hot air coming out of it, but not much else is happening. The entire system was working perfectly until a few days ago. Of course, this coincided with a nasty winter storm in the So. Calif. area... The temperature in my 400 sq ft loft apartment is getting down into the upper 50s at night -- and I'm FREEZING!! Can you guys help me out?? Carrie
