DOA. Being a professional I should have known not to buy this no name brand. But I thought I would save my customer a little money.It looks right. Would do pre-purge and power-up the ignitor. But as soon as it sent power to the gas valve it would shut down. Lights would go out. Only way to get it to retry was to power off.I even unhook gas valve and put my meter on the wires feeding it. Same thing, 26 volts for a split second then shut down.Sent back and order a OEM from one of my supply houses.

Works like a champ, solid.Packaging could be a little more water resistant though.
