--- title: "Dryer with no heat" description: "Kenmore dryer with no heat — a dryer that turns but does not heat has a short list of causes, and which list depends on whether it is gas or" url: "https://kenmoremiami.support/symptoms/dryer-no-heat/" date_modified: "2026-09-01" Appliance type: "Dryers" --- # Kenmore dryer with no heat ### Check the breaker, both halves of it The motor in an electric dryer needs one leg of the supply and the heater needs both. Lose a leg — a double breaker tripped on one side only, which often does not look tripped at all — and the machine tumbles happily and never warms up. It is the single most common cause of this exact symptom and it is not a dryer problem at all. ### What it usually means, by the company that built it Kenmore manufactures nothing, so the same behavior points at different things depending on who made the appliance. The three digits before the period on the rating plate are what tells them apart. - **110 Whirlpool** — F4 E1 is the heater or its relays. F4 E4 and L2 are Whirlpool's codes for low or no line voltage, which they put at the house supply rather than at the dryer. - **796 LG** — Ps is LG's POWER ERROR. On a gas machine, gAS is the only gas-specific code LG publishes and it means no gas supply. - **417 Frigidaire** — No published table. Diagnosed by measurement at the appliance. ### Two dryers, two shortlists An electric dryer heats with an element and protects it with thermal cut-offs. A gas dryer heats with a burner and protects it with a flame sensor and a valve. Neither list contains the other’s parts. This is why the very first question is which one you have — not to be thorough, but so that the van carries the right box. ### Why we always look at the duct on a no-heat call The thermal protection in a dryer exists to shut the heat off when air is not moving. When it has done its job, the honest repair is to restore both the protection and the airflow. Replacing the part and leaving the duct is not a repair; it is a delay. Half the electrical supply is missing Whirlpool's own codes name the house supply for this. Reset the breaker fully — off, then on. The gas supply is off On a gas machine. Check other gas appliances in the house before assuming the dryer. A thermal cut-off has opened Usually because of a restricted vent. Replacing it alone gives the repair a return date. The heating element On an electric dryer, and it is a straightforward part. The igniter, flame sensor or valve coils On a gas dryer, in that order, and they are tested rather than swapped — all three produce the same complaint. The control or the thermostat Where the heat circuit is intact and nothing is asking it to work. Gas or electric The most important thing you can tell us about this symptom. Cycle the breaker fully All the way off, then on. A partly tripped double breaker looks fine. On a gas machine, does the stove light It establishes whether gas is reaching the house at all. Check the vent while you are there Because the protection that shut the heat off opened for a reason. It tumbles perfectly and nothing gets warm What it usually means Gas and electric fail in different places An electric dryer on one leg of supply does exactly this The vent is checked in the same visit, always Check the breaker, both halves of it The motor in an electric dryer needs one leg of the supply and the heater needs both.

That is a protection cycling, and it is the vent almost every time. ### My dryer is gas — does that change the price? It changes the parts and it needs a licensed technician, so yes. The page for it says so before the figure. --- **[Read full article: Dryer with no heat](https://kenmoremiami.support/symptoms/dryer-no-heat/)**
