Does anyone know what trouble code this is? light comes on for about 5 seconds then, it blinks three times(short). I don't have the owners manual. This is a Day & Night Model number 373LAV048075. I get 27.7 volts on the transformer. The inducer motor does not come on (no power to it)no power to the hot surface igniter or the high limit switches. Blower comes on when set to fan on. Any suggestions, will be appreciated.

Our Oil Furnace (Beckett AFG with Honeywell R8184G controller) fires and runs for about 20 seconds, loses flame, and the safety trips. We routinely replace nozzle and oil filter about 3 times each heating season. Just replaced last week. There is a good ¾ inch plus hot spark from the transformer (checked across contacts). Electrodes are in fair shape, but are a few seasons old. Cad cell is showing about 450 ohms with bright light, 100,000 ohms in dark. It was replaced last year. If I push the reset, the furnace fires quickly and without rumble or smoke. 20 seconds later the flame stops; but the pump continues to run. I have been tripping the reset after about 2-3 seconds to avoid putting a lot of oil into the combustion chamber. Had the same problem three days ago. After checking everything I could, I gave the oil pump a light rap with a crescent wrench (theory of the bigger hammer). It worked great for two days! I do not recommend this as a repair technique, but I thought that there might be a clog that could be freed up. We are back to the 20 second flame! I disconnected the cad cell from the controller. Started the furnace (it fired) and immediately jumped the cad terminals (F terminals). In theory, the furnace should continue to run. Nope……20 seconds, fire out; pump still running. According to the Oil Controller manual, this indicates a faulty controller. I also understand there was some sort of a recall on Honeywell R8184G units. My questions are: 1. Should I check anything else? 2. Any concurrence that the Controller is the culprit? I have the techs with the measuring devices come out to do fine adjustments after the furnace has been in use for a month or so for "shakedown". We live out in the country, and service calls are expensive, so I try to take care of all I can to better use the service tech when they get here! Your help is greatly appreciated, Pat :wall:
