That sudden drop in temperature isn’t a malfunction, it’s energy moving exactly as it should.
When you load dough into the Simply Bread Oven, the stones beneath your loaves are hotter than the dough. The moment dough touches the deck, heat flows into it. The oven’s display shows this as a dip, but what you’re seeing is thermal transfer in action: heat moving toward balance.
Thermal transfer is the movement of heat from a warmer object to a cooler one until equilibrium is reached. In ovens, this happens in three main ways:
• Conduction — direct contact, like dough against a hot stone
• Convection — heat carried by moving air in the chamber
• Radiation — energy radiating from the top coils
Most home ovens rely on convection and radiation. A Dutch oven traps that heat inside its metal walls. The Simply Bread Oven works differently. As a stone deck oven, it bakes primarily through conduction, meaning heat moves by direct contact.
When cold dough lands on the stone, it immediately begins pulling energy out of it. The stones are acting like batteries, releasing what they’ve stored into the loaves. As that transfer happens, their surface temperature falls. At the same time, the chamber air above the stones cools, which is what the oven’s sensors are measuring. They don’t read the stone surface directly. They read the ambient air just above it, which is cooler once thermal transfer begins. What you see on the display is this combined effect: the stones are giving up surface heat to the dough through thermal transfer. The dough is literally robbing that surface temperature to fuel its bake. At the same time, the oven chamber air cools because you’ve just loaded cold dough and in some cases, added steam. The air sensor only measures that cooler air, not the heat still stored in the stones, so the display shows a drop
The dough isn’t just sitting on the stones, it is actively pulling stored heat from them as it bakes. Once the dough has taken the energy it needs for spring, the final burst of rise in the oven, and to bake through inside, the stones begin to recover in temperature. That recovery is slow and usually does not finish during the bake itself. Full recharge happens in between bakes, as the stones rebuild the heat they need for the next load.
Once you understand the dip in temperatures, it stops looking like failure. Your oven isn’t losing control. It’s feeding your bake. Every bake you load pulls energy from the stones, and every stone responds by giving that stored heat directly to the dough.
But energy is not infinite. After a full load, the stones need time to recharge. If you reload before they recover, they can’t hit the dough with the same intensity. That’s when you see weaker spring, pale bottoms, or color differences between decks.
Temperature recovery is gradual, and it doesn’t happen all at once across the oven. The top deck climbs back to temperature first, the second deck follows, and the bottom is always the last to catch up. When the oven beeps to signal that it has reached temperature, what it’s really showing you is the average of all three sensors. That average can hide the fact that the bottom deck is still lagging behind, even though the display looks ready. If you load too soon, that lower deck won’t have the power to drive proper spring. Giving it a little more time to fully charge ensures that each deck has the energy it needs to fuel the bake.
The amount of product you load changes how the oven’s stored energy is released.
With a full deck of 12 loaves, the stones transfer heat into a large mass of dough. That energy is divided across many loaves, so the bake progresses at a measured pace. Crusts open gradually, spring develops fully, and color stays balanced.
With a smaller batch, say 4 loaves, the same stored energy has fewer places to go. Each loaf receives more of it, so the bake runs hotter and faster. Recovery between bakes is also sharper because less dough absorbs the charge.
This effect is most extreme with low mass products like cookies, scones, muffins, or rolls. These items absorb very little energy before setting, so the stones release their charge almost immediately. Timing becomes critical, and products can color or firm up faster than expected. Learning your optimal temperature and load balance ensures consistent color, spring, and bake speed
That’s why small or light loads may require adjustments. Lowering the preheat by 10 to 15°F reduces the initial surge, keeping thermal transfer in balance with the amount of dough you’re actually baking.
Some bakers lower the oven temp right after loading. This can work, but only if you understand what’s actually happening.
Dropping the temperature doesn’t instantly cool the oven. What it really does is turn the coils off until the chamber air falls to the new target temperature. If you preheat to 500°F and then lower the setting to 450°F right after loading, the coils won’t cycle back on until the oven air cools all the way down to 450°F. In practice, that can mean the coils don’t cycle back on at all during the bake, leaving the top underpowered. The stones are still hot and still pushing heat into the base of the loaf, but without top heat to balance it out you can end up with darker bottoms, pale tops, and uneven results.
If you’re choosing to turn off the coils this way, set a timer. Turn the oven back on to your original preheat target after about 10 minutes. That reengages the top heat, restores balance between the deck and the coils, and keeps your bake on track.
What looks like a temperature drop is actually your Simply Bread Oven performing exactly as it was designed. The stones aren’t failing, they are quietly delivering the energy your dough needs to rise, color, and develop structure. Understanding this shifts the way you bake, giving you confidence to trust the system instead of fearing it.
That energy is also what makes baking directly on the stones possible. Bread, rolls, bagels, even delicate cookies or scones all benefit from it because the stones are the heart of the bake, consistently fueling your dough with stored heat.
But that same strength comes with rhythm. Like any source of power, the stones need time to recover. Rushing them into another bake too quickly weakens their impact, showing up as flatter spring or uneven color. Make sure to give yourself plenty of time to reheat.
When you learn to trust that rhythm, the oven becomes an ally. You’re no longer chasing numbers on a screen or second-guessing your process, you are working with the oven itself. And that’s the key to consistent spring, balanced color, and predictable results every time.
