SO...here is how I went prepared.
1. Suburban 42k FURNACE with couple propane tanks
2. Electric Oil radiator heater in garage
3. Electric fireplace in camper
4. little electric space heater in cabin
5. Sleeping bags and wool blankets
6. EXTREME WEATHER PACKAGE......I know, I know, I know
7. YES....50 amp service so I have plenty of juice.....
8. no water, just using window wash as emergency toilet use if needed
9. super hot wife(looks and temp) to snuggle up next to....
Keep in mind that the high for the week is looking like 15 deg F. When I hooked up it was 0 on the truck dash. 5 for a high on Sunday with an overnight low of -2. We cranked her up to 65 and went to sleep. 2:30am the furnace decided to take the rest of the day off....OH SNAP! Here we go.... Kept really nice under blankets and son was great on couch with sleeping bag, but it did get down to about 48 in the cabin.
I thought the tanks I had were empty so I grabbed n headed to town for fuel...nope. Heater just quit after 7 hrs of running. Filled tanks anyway so felt better. Hooked up and turned on. Fan ran, lighter ignited...off...cycled twice again. NO GO! Spent the next 3 hrs following FR Forum on furnace issues...reset valves and regulator...slowly! All that...finally took outside cover off and reset switch on motor...started to cycle, ignition, gas, heat...off.
After 3rd cycle I used the primitive method of the fist rapidly on the fan motor shaking the whole damn thing.
After 3-4 repetitions of that I have had heat for 16 hours...EUREKA! Bang on it in frustration!!!!
OK....set thermostat at 63 with electric heaters and was AWESOME ALL NIGHT. Furnace only cycled 2x per hour for a few minutes and we all were toasty warm all night. 2 down and 4 to go. I will follow up with detail
