SOURCE: Bosch HGS442UC Gas Oven won't light

Usually when an oven won't bake, it's because the bake igniter is weak or burned out. The igniter is a small, round or rectangular device, that's about 1 inch by 4 to 8 inches. It's near the burner itself.

The burner is the tube-type device the gas flows through before it's ignited. It has many small holes on the sides to let the gas, when ignited, form a long, low flame. If the igniter is weak, if it glows red but doesn't get hot enough, or if it's burned out, the gas doesn't flow to the burner and the burner won't ignite. If this is the problem, you may need to replace either the igniter or the gas safety valve. Usually the igniter is to blame.

Other causes Other reasons that your oven may not bake are:

  • The clock settings are incorrect (if you have timed baking or a self-cleaning oven).

  • The thermostat is defective.

  • The safety valve that prevents accidental gas flow is defective.

  • The selector switch is defective.

make sure the hose is connected to the propane tank and that the tank valve is opened letting gas into the grill exhausts... and then light the igniter but make sure the release valves on the grill arent on max... start it on low to med.

It is possible. There are a variety of replacement knobs. THere's two websites that you should check out. One is Go there with your make and model and it will walk you through the rest. The other would be Bosch's site itself.

Hi.. have a 300 series weber we bought only last year.. I cannot get the burners to come on together.. I can manually light the inner one but as soon as I try and manually light the outer one... it will...

More than likely, the grill's regulator is malfunctioning. To solve this, turn the LP Gas Tank Valve OFF and disconnect the hose. Turn the grill burners ON, wait 2 minutes and turn them OFF. Reconnect the hose to tank and open the tank valve VERY, VERY SLOWLY (Slow motion, slow) Once the valve is open all the way, light the inner burner first and turn it to the highest setting. Does the flame height look correct? If so, light the outer burner and turn to HIGH. Do both flame heights now look correct? If so, you solved the problem.

If you are using an insert-able gas canister, instead of a 20Lb LPG Gas tank, do the same thing as above, except remove the canister. Since there will be no hose/regulator assembly involved.

To provide further assistance, in case you have misplaced your Owners Manual, I have included a link to it that you can download and print for future reference, if you like.

Hope this helped you to solve the problem. Please let me know and Happy Grilling!!

Grill won't ignite. full tank, wires look OK. model is the second smallest weber Q.

If you're not getting any gas at all to the burner and you have a full tank pf LPG ... Turn the tank valve OFF and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Now, turn the tank valve ON VERY, VERY SLOWLY (slow motion, slow). Once the tank valve is fully open try lighting the burner. If lights, turn it up to the highest setting. Does the flame height look correct? If so, you solved the problem. Just remember to always turn the tank valve on VERY, VERY SLOWLY.

If you were getting gas to the burner and the ignitor wasn't sparking, pull the wire of the needle like pin on the bottom of the piezo spark ignitor. Then slide it back On. That should solve the sparkless problem.

Hope this helped you solve the problem.

Hello, we have a 3 switch stainless grill that has NEVER heated up properly. It always seems to stay luke-warm. Please help.

First, how high are the flames when turned to high as opposed to the low setting on each of the 3 burners? If there's no significant difference in height between the two settings, here's what I want you to do.

Turn off the gas tank (that's assuming you are using a 20lb LPG cylinder) and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Turn the Tank Valve ON very, very slowly, until it's fully open. Now, light each burner individually turning them to high. Are the burner flames higher than before? If so, you just solved your problem.

Remember to turn the tank ON very, very slowly after turning it off to change the tank or if you turn the tank off after each time you grill. Also, when grilling preheat the grill with the lid closed, after lighting the burners.

Hope that solved your problem ... Happy Grilling!

When one of the gas hobs is on ,it does not burn with a blue flame but a more yellow one .also black soot forms under the burner is on lpg

Have to adjust the piolot lights for the amount of gas coming out. U have too much gas coming out(yellow flame). On older gas ranges, there was a small screw between the piolot light & burners that had to be adjusted. (if this is a older model) have to turn the screw just a little at a time, till ur flame returns to blue on ur burners. Hope this helps.

Doesn't seem to be enough gas going into the

Hi am welcome to FixYa. I am Kelly.

1. Does the LPG tank have gas in it?
2. Is it one gas control or more that gives you this symptom? If it is more than one and there is gas in the LPG tank then the LPG regulator can be the problem.
3. There can be debris on the face of the gas orifice where the burner mates to to the gas control selector assy. (Spider webs / grease /dirt)
4. The air hole in the burner can be partially blocked with something (same as above Grease, dirt, cob webs)
5. The holes in the burner itself can be corroded or blocked with something. (This one would be pretty obvious)
6. The gas valve 'heat control may not be functioning properly.
7. There is a very remote possibility that the LPG hose has collapsed.

I would check the orifice and the burner holes for obstructions after verifying the LPG tank is usable. Then the next suspect would be the LPG regulator.

Thanks for using FixYa,

Gas Grill Burners with yellow flames coming from beneath them

the flames should be blue and the burners clean. check gas pressure and the air mixture dampers. touch air will give you the same effect. if the burners are clean, it is the mixture. as far as the slots in the bottom. i have not seen that. but i work on commercial ranges.
