Is Your Oven Good for No-Bake Cookies and Nothing Else?
Is there anything more useless than an oven that won’t heat up? Especially when you have an insane craving for fresh-baked chocolate chip cookies!
If you’re stuck in a rut making no-bake cookies because your oven just won’t heat up anymore, you’ll probably have to call a repairman to restore your oven to working order. When he arrives to investigate the problem, odds are good that it will stem from one of the following common causes:
If you have a gas oven, you might be having problems with the igniter. The igniter, of course, has the job of lighting the gas flame when you turn the oven on. Even if you see that the igniter is glowing, it may still be the problem. It’s not uncommon for igniters to weaken enough that they won’t light the gas, even though it’s apparent they’re still glowing.
Failed igniters are the most common cause of gas ovens that have problems heating up.
For electric ovens, the element is the most common cause of a failure to develop heat. The elements – both the baking element and broiling element – will glow red-hot when they are working normally. So this problem is easy to check with just a visual inspection. And sometimes elements will even develop blisters or burned-out portions that are easy to spot visually.
Elements cannot be repaired. If yours has failed it will have to be replaced.
Most ovens have a thermal fuse designed to prevent the appliance from overheating and catching fire. If the thermal fuse has blown, it will prevent the oven from heating up. Some fuses can be reset; others must be replaced after they’ve tripped.
The control board relays signals from the control settings selected by the user to the appropriate internal circuits. Though rare, control boards sometimes develop defects that cause them to malfunction. When this happens the only recourse is to replace the board.
Gas Valves and Pressure Regulators
Gas ovens have valves that regulate the flow of gas to the burners. If this valve fails it can prevent gas from reaching the burners. Though valves do fail, it’s a rare occurrence. If gas isn’t getting to the burners, it’s more likely that a bad igniter is preventing the valve from opening.
Similarly, the gas pressure regulator can sometimes fail, also preventing a sufficient flow of gas to the burners. As with failed valves, pressure regulator failures are quite rare.
Electrical ovens sometimes develop problems with the wiring that supplies power to the elements. Sometimes this wiring can loosen, or can burn out. A common point of failure is at the location where the wire connects to the element.
