Service bulletin TSB 20-04

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Certain model year 2019.5 Chateau, Four Winds, and Quantum 31’ motorhomes may experience problems with the gas burner igniting on the cooktop. This may be due to the cooktop being a second-generation TI-1+2B combination gas/induction cooktop which requires a 12-volt power supply wire from the distribution panel. This 12-volt power supply wire may be missing.
