Model 790, burners ignite, but broil or bake does not. found 'regulator lever' on back but can't tell which direction is on.

Hello. There is *no* pilot on this range! You have a glow bar for both the bake and broil functions in the oven. The bake glow bar part number is (#19) 316489402(see pic 2). The ignition module(that provides the high voltage for the spark posts at each of the surface burners is (#8) 316262400. The ignition harness(that has four ignition switches daisy-chained together is (#3) 316580615. The sealed burner for the LF and LR is 316558300(quantity 2). The RF burner is 316438600. The RR burner is 316438200.

If you are hesitant about the disassembly on the range, I strongly advise calling for service--The cooktop must be removed to exposed the ignition parts. This is accomplished by releasing the burner heads from the cooktop. The mount screws on the burners are notorious for seizing and the heads breaking off on removal. If this happens, the orifice/ignitor will have to be replaced for every burner with which this occurs. It can be expensive! I hope the diagrams and part numbers help you!

There is a service flash, W10622771, for gas ranges of your model number--the bake burner ignitor is not lighting the gas--it's a direct spark ignition type. The ignitor is sparking but no ignition. Possible causes are (1) Wiring harness might be pinched between the bake/broil ignitors and the DSI board. (2) DSI mounting bracket may be contacting a solder joint on the back of the board. (3) Positioning of the ignitor and gas burner ignitor ports may be out of adjustment. (4) Ignitor electrode deterioration
Facing the range, the DSI board is behind the control panel on the left side, mounted in the bracket.You'll have to remove the back cover to expose the boards. BE SURE TO UNPLUG THE RANGE BEFORE DOING THIS. I can provide diagnostic mode if you want to proceed further.

Assuming this is on a gas range, the bake burner ( under the oven floor) and the broil burner ( at the top of the oven) have electric igniters . When switching from bake to broil the broiler goes off due to a defective or broken broil igniter. cheap part to replace ( +-$40.00)

Hello there:
It doesn't bake Bake igniter
When the bake igniter becomes weak or burns out, your oven would not bake. The bake igniter is usually mounted on the oven burner. It's about 1 inch by 4-8 inches (depending on the model), and comes in round or flat styles. If you don't see the igniter glow at all, it's probably burned out. Replace the igniter if found defective. Note: one of the exceptions could be that your oven is set to automatic mode instead of manual. If this is the case, set your oven to manual mode and check again.

If the bake igniter glows red and not bright yellow or white, it is probably because it is too weak. When this happens, the safety valve would not let the gas out into the oven burner. A weak igniter must be replaced.

A faulty igniter is probably the most common cause, however there are others:

-- defective thermostat
-- defective selector switch
-- defective gas safety valve

If you are certain the igniter is ok, it might be a good idea to call a professional appliance technician.

Hello there: The oven bake burner and ignition components are located beneath the oven cavity. In most cases the oven bottom panel can be removed for access (check your owner's manual) but on some models the oven burner has to be accessed from below in the warming or broiler drawer area. If accessing from the top, a 'flame spreader' (flat metal plate) above the burner may also need to be removed to see the burner itself.Many ovens use a single oven burner in which case they only have a single gas valve and ignitor. The same burner is used for both bake and broil functions, the broil usually being in the drawer area below the oven. Higher-end models may have a separate bake and broil burner. On such a system there will be two ignitors, one for each burner. They may also employ a 'dual' gas valve (see illustration above) instead of using a separate valve for each burner.Some range models may have an additional broil burner located at the top of the oven cavity which may be referred to as a 'waist high' broil. If not, broiling usually takes place in the drawer area below the oven, which uses the same bake burner for the broil function. Most gas ranges currently available employ one of 3 basic gas ignition systems; pilot ignition, hot surface ignition system (which uses a 'glow bar' or 'glow coil' - aka an "ignitor") and a spark ignition system. The latter two being referred to as "electronic ignition" systems as they use electricity in one form or another to operate the oven heating system. Only the pilot ignition system has an actual "pilot" (which is a small but real "flame") which might need manual lighting.
If the surface burners of a range are a spark ignition type, the oven IS one of the possible kinds of electronic ignition systems and thus will not usually have a "pilot" which needs lighting. Be aware though that just because the surface burners might light via a spark doesn't necessarily mean the oven uses the spark type ignition system too.
There is one older style of electronic ignition system which does also use an oven pilot but it is very rare and such a system hasn't been used in oven models since the early to mid 70's. It is the 'constant pilot' *electronic ignition* system.


Making Observations
The oven burner's operation will usually need to be directly observed while in operation as the first step to troubleshooting problems.Ignition System Type Links
Ignition System Types:

Pilot Ignition

Electronic Ignition with Constant Pilot (rare)

Electronic Ignition with Glow Ignitor (most common)

Spark Ignition System

Is there continuity between the oven gas valve's terminals?


Hot Surface ('Glow Bar') Ignition System (most common)
This is the most popular system currently used for ovens and is comprised of a control mechanism (whether thermostat or electronic control), the oven ignitor and an oven gas valve.


What happens in this style ignition system is that the thermostat or electronic control switches power to the oven ignitor and gas valve circuit which are connected in series (one after the other). As power flows through the ignitor it heats and draws current (measured in amperage). Once the oven ignitor draws a specific amount of current the oven valve opens to allow gas to flow to the oven burner where the glowing hot ignitor (glow bar) ignites it. Power must continually flow through the ignitor and oven gas valve for gas to be released into the oven burner to create a flame.

It should usually only take in the area of 30-90 seconds for the oven ignitor to reach the proper resistance to allow the proper amperage to reach the gas valve to open it and for the ignitor to ignite the gas at the oven burner.

Probably need to replace the igniter. Swap the broil and bake igniters and see if the problem follows the igniter. I just had this happen to mine. Glow bar/igniter appeared to be working properly but was weak causing the regulator valve circuit to keep the flames very low. Swapped ingiters as instructed and problem went with the bad igniter to the broil/top burner.

The igniter in the oven does not spark. It heats up and glows red hot until enough current opens the safety gas valve to the burner. It is not associated with the stovetop burners. Replace the oven igniter itself.

Kenmore oven 790.91072601, bake & broil not working, relays are cycling but no heat... Sounds like I have the same problem but its the night before Thanksgiving and Iam in panic mode... I've orderd a new Temp Probe part # 316233902. did you ever get yours fixed

i have a 900g stoves oven how do you change from auto to manual

Very well could be. I'm assuming the bake burner is the problem, right? Does the igniter glow at all? If it is glowing, but the burner does not light, is it usually a symptom of an igniter that has become weak. If it does not draw enough current the gas valve will not open and the burner will not light. This is a safety feature to prevent free flowing gas without ignition. If the broil burner is functioning properly, then more than likely the gas valve and regulator are working fine. In most ranges both burners are fed from the same source. You could try swapping igniters between the broil and bake burners to prove the theory. Or, you could just replace the igniter all together. Current readings are as follows: Round shaped glow igniter: 2.7 to 3.2 amps Square shaped glow igniter: 3.2 to 3.7 amps If you can give me the exact model number off your range (usually located around the oven door or on the back of the range) I can give you the correct part number you will need. Most appliance repair stores carry the igniter. I hope this helps you.
