We regret the trouble you have experienced with this gas range. The F19 error code suggests that the oven is not heating. If the current lower oven temperature does not exceed 150 degrees, or is lower than start temperature after 5 min of pre-heating, then the range may require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at http://www.lg.com/us/support/repair/support-repair-provider-lookup.jsp.
