Yes, that's a fair assumption. The N306 has no circuit board. If it cools on propane but not on AC, it's usually the AC heater. Measure its resistance: open (infinite) means it's bad. The 630809 fits the N306. The selector switch or its wiring can also cause this, but the heater is the most common.
