An oven that won't stay lit could be due to a faulty or weak igniter, gas supply problems, or clogged burner ports, which are common culprits for this issue. A weak igniter is often the primary cause of a gas oven not staying lit, necessitating replacement by a service technician to ensure proper heating.
Your gas oven could be turning off because its ventilation system is blocked. Additionally, your gas ignitor could be damaged or failed to light, you could have a broken thermostat, or you may be low on gas. Finally, your gas line may be blocked.
To replace your oven sensor, you'll pay between $100 and $250.
The thermocouple is a device that sits at the edge of the flame... This device warms in the flame and sends a 30mv signal to the gas valve to open, allowing full amount of called-for gas to the oven... If the thermocouple cannot sense the flame, then it sends no signal and therefore the valve closes and wont stay lit.
A lot of modern ovens come equipped with a protective safety measure to stop them from overheating. This typically comes in the form of a circuit breaker, cutting power to the oven in the event that it gets too hot.
There's really just one telltale sign of letting you know when the thermocouple isn't working, and that's when the pilot light won't stay lit. If you experience this problem, it's important to have your thermocouple assessed as soon as possible.
The rule of thumb is that if repair costs exceed 50% of the price to install a new oven, you should buy a new oven instead of replacing it. For example, if your oven costs $2,000 but costs $1,500 to repair, you could use that $1,500 for a new and improved oven.
Make sure the multimeter is calibrated and then turn the dial to the lowest ohm rating. Place the multimeter on the thermostat. If the thermostat has a reading of zero or as close to zero as possible, it is working fine. However, if it has no reading at all, your oven thermostat is faulty and will need replacing.
Turn the circuit breaker to the OFF position or remove the fuse. Wait one minute, then turn the circuit breaker back to the ON position or install the fuse to reset power to the appliance. This should reset the electronic controls on the Range or Wall Oven.
Depending on power setting and number of burners in use, burners on an Electric Cooktop may shut off as a precaution to avoid overheating. Turn the home circuit breaker to the unit off for 30 seconds and back on again.
Check Ventilation: Ensure that the vents and fans are not obstructed, allowing proper airflow. Reduce Cooking Time: Try reducing the cooking temperature or time for the dish you're preparing. A malfunctioning thermostat can also lead to oven shutdowns.
Some of the most common issues include accidentally unplugging the stove, excess food debris, or the gas not being connected properly. While there are many DIY solutions for simple issues, it's usually best to call a service professional to help troubleshoot.
Gently scrub any corrosion or oxidation on the thermocouple tip using very fine steel wool or a green cleaning pad. Take care not to bend or damage the internal sensor.
The life expectancy of an electric oven is around 13 - 15 years. The life expectancy of a gas oven is around 15 years. The life expectancy of a dual-fuel oven is also around 15 years. However, the lifespan of these kitchen appliances depends on how frequently you use them.
If the oven is receiving power, various issues could be preventing it from turning on. Common electric oven problems include a broken wire; a bad control, a bake, or broil element; or the wrong amount of power coming to the unit. Common gas oven problems include a faulty gas control, igniter, or valve.
Considering ovens can last 15 years (and sometimes more), it is likely a better idea to repair a 10-year-old oven, assuming the repair won't cost more than 50% of the oven's value. So, for instance, if your oven is worth $1,200 and the repair is only $400, it's a better option to complete the repair.
To test a temperature sensor with a multimeter, set it to measure resistance, clip one probe to an outer sensor connector and the other across from it. Submerge in hot then ice water, note readings after a few seconds - around 250 and 1000 ohms respectively.
If your oven is not maintaining the correct temperature, it could be due to a malfunctioning thermostat, a faulty heating element, or a malfunctioning temperature sensor. The issue may also simply be a need for calibration or keeping the door closed.
Cost to fix oven sensor
The cost to fix an oven sensor is $100 to $250 for replacing the part or more with OEM parts and wiring. This sensor alerts the control board to the current oven temperature.
Replacing a thermocouple is a relatively easy fix that can take less than two hours. This guide reviews how to replace a thermocouple to ensure gas appliances stay in good working order, as well as how to relight a pilot light.
Clean the Thermocouple: Use a brush or compressed air to remove any debris or dust on the thermocouple. A soft-bristled brush works well for this. Handle with Care: Be gentle during cleaning to avoid damage.
The thermocouple is a safety device designed to shut off the gas valve if the pilot light goes out. Although, if your thermocouple is old, worn, damaged, wrongly positioned, or malfunctioning, it could have wrongly shut off the gas valve and prevented your pilot light from staying lit.
