Danby Oven Thermostat 310220009 – Fixes Oven Not Holding Temperature (WYE-175)

When the oven thermostat fails, your oven loses the ability to regulate heat accurately — it may overheat, underheat, or cycle erratically, ruining meals and making baking impossible. The thermostat is the core temperature-sensing component; without it functioning correctly, no amount of preheating or adjustment will produce consistent results. This is the genuine OEM replacement (310220009 / WYE-175) for Danby ovens.

⚠️ Symptoms of a Failed Oven Thermostat

• Oven temperature too high or too low compared to the set dial
• Food burning on the outside but raw in the middle
• Oven takes excessively long to preheat or never reaches temperature
• Oven cycles on and off erratically during cooking
• Baked goods consistently over- or under-cooked at the same settings
• Oven runs continuously without shutting off at the set temperature
