LP trouble that shows up with cold weather usually comes down to gas supply or ignition. Here's where I'd look:
- Propane pressure drops as the tank gets cold, especially when it's low. Make sure the tank is full and check that the regulator isn't icing up. - Pull the outside access panel and watch while it tries to light. If there's no spark, the spark sense electrode 61692222 is a common culprit on the N641. - If it sparks but won't light, clean the burner and orifice. Also check whether the gas valve is clicking open. The gas valve 621334 fits the older N6 models, but it's discontinued and stock is limited.
If there's a code on the display, let us know what it is and we can narrow it down.
