Caloric oven doesn't work

Hi, I have a 1987 Caloric spark assisted pilot gas range model #RMS379 UL. The top burners work fine, but the oven will not work. The oven pilot lights but the flame is not strong enough to reach the thermocouple bulb. I have changed the pilot insert and still have the same problem. Is there anything that controls the flame pressure so it reaches the thermocouple bulb. Thanks for any help you can provide.

Mike

Hello Mike and Welcome to the Do It Yourself Web Site and to the Gas Appliances topic.

Most likely the pilot orifice, inside the pilot assembly, is restricted. Thus restricting pilot gas flow. Clearing out the debris from the orifice and the pilot flames tube/holes/slots, depending upon pilot assembly type, usually works. Worth a first try attempt. Here is how to do this.

A can of compressed air used to clean computer keyboards usually works. Insert the plastic extension tube from the can into the secondary air holes in the pilot assembly, just behind the pilot flame and right after the assembly nut. Blow air into both of those holes. The trick is to direct the air at the orifice which is facing the holes. Then do this from the opposite side through the other air opening hole.

Then blow air into the hole(s) where the flames appear. The method used to do this and the above varies based on the type of pilot assembly used.

One of the pilot assembly types could be horizontal with several flame ports and one type with only one large flame hole, etc. There are several types.

Usage of an small children's type tooth brush can be used to clean the ports on the horizontal type pilot assembly. Also can be used to clean the ignition ports where the pilot light flame ignites the burner flame. Once that is done, use the compressed air to blow out the entire assembly.

Objective is to clear the pilot assembly without having to remove and disassemble it, clean it and reinstall it, if possible. Once the cleaning is done, test it.

If the above method works, task done... If not... the entire pilot assembly needs to be removed, cleaned and reinstalled. Use caution. The parts are rather tiny, get lost easily and or can break easily, etc.

Cautionary Reminder Note:
Before attempting any repairs, be sure to unplug the appliance from the wall receptacle power source first.
