Question about Blodgett DFG-100 Gas Single Oven

Gas smell at start up

Hi, I'm dealing with an older Blodgett stack oven Model DFG-100-3, S/N 0785R4705101 with hot surface ignition. Every morning at start up we get a strong gas odor. Once unit fires and heats up to temp, no noticeable smell is detected for the rest of the day. I am just guessing here but can the ignition module be turning the gas on prematurely at startup? Should I be looking to replace the module or is there something else I should be looking for? Thanks.

    no The gas valve should not open until the coil (ignitor) is glowing hot unless you have a leak in the tubing or valve itself

The ignitor and the module work hand in hand to make sure the gas valve doesn't open until the unit is ready. If you are smelling gas on startup, but not before startup, the module is a good suspect. I could definitely replace the ignitor with it as a set.

Be sure that the igniter has a good ground. I mean make sure you clean it well. Be sure its fastened well. And of course that it is close enough to burner. Air flow in building can also hinder lighting.

    Once the exhaust is warm you will have an updraft and you will be unable to smell gas as it will go up the vent. You may actually still have a problem just unable to smell it. .

Igniter stays lit entire time oven is on Blodgett dfg 100-1

I have seen this happen when a hole develops near where the ignitor is mounted. The excess gass overheats the ignitor and burns it up. What I do in a case like that is slide a c clamp over the burner and cover the hole.
