Dryer Not Heating? Causes, Tests and Costs in Arizona

If your dryer runs but does not heat, check the 240 volt breaker first, then the vent, then the thermal fuse and heating element. In Arizona a pro charges $100 to $280 for the fix, and the first two checks are free.

Dust storms, long roof vents and monsoon power outages cause some of the Arizona only problems. This guide gives the tests in the order a pro runs them, with the price of each fix.

• Check the power first. An electric dryer needs 240 volts, and a breaker that looks on can still be the problem. Free to fix.
• Check the vent second. A clogged or crushed vent is the top reason the heat quits, and it kills parts if you ignore it.
• Thermal fuse next. It is a one shot safety part. A pro charges $80 to $180, and you can do it yourself for the price of the fuse.
• Heating element after that. A pro charges $150 to $280. Test it before you buy one.
• Gas dryer? Open the gas valve, then call a pro. Igniter and coil work runs $120 to $230.
• Never bypass the fuse. It is there to stop a fire.

Do these before you spend a dime. Most of them take less time than reading this page.

Run an empty heated cycle. Maytag tells you to pick a heated timed cycle, run it for 5 minutes with the drum empty, then open the door and feel inside (Maytag product help). If it is warm, the dryer works and your problem is airflow or a wet load.

Look at the setting. Air Only and Air Fluff cycles never add heat. Eco and cool settings are low on purpose. Pick a normal heat setting and try again.

Clean the lint screen. Pull it out, wipe it, and hold it up to the light. A film of fabric softener can block it even when it looks clean.

Check the breaker. Maytag says an electric dryer runs on its own 30 amp circuit with two breakers, one for the motor and one for the heat. Either one can cause no heat. Flip the dryer breaker all the way to off, then all the way back on.

Gas dryer. Make sure the gas shutoff valve behind the dryer is open. The handle should line up with the pipe. If you ever smell gas, leave the house and call your gas company.

The wall outlet in the photo is the kind most electric dryers use. If the plug feels loose, looks burned or the cord ends were never tightened, stop and call an electrician. Maytag also says the terminal screws at the back of the dryer should be tight, with the dryer unplugged first.

The drum is turning, so the dryer has power. But the drum motor uses half of the 240 volt supply. The heater needs both halves. If one side is dead, you get tumbling with no heat.

How to test it. Turn the breaker fully off and on. If heat comes back, you are done. If it trips again, do not keep resetting it. Something is drawing too much power and an electrician needs to look.

Cost. $0 for a reset. DIY friendly. A pro dryer repair call starts at a $75 to $150 service fee, so a reset is worth trying first.

This is the one to fix even if it is not your main problem. Hot air has to leave the dryer. If it cannot, the dryer overheats and shuts the heat off to protect itself. That is also how parts burn out.

The U.S. Fire Administration looked at home dryer fires from 2008 to 2010 and found failure to clean was the leading factor at 34 percent (USFA report summary). Lint and dust were the first thing to burn in 28 percent of those fires.

How to test it. Pull the dryer out, disconnect the duct and look inside it. Then go outside and check the hood. The flap should open wide when the dryer runs. Whirlpool says to keep the hood at least 12 inches off the ground or any object, and to use 4 inch metal duct, because foil and plastic crush easily (Whirlpool venting help).

Cost. Free to $20 for a brush kit or new duct if you do it yourself. Follow our dryer vent cleaning guide. If the dryer is new and the vent is old, a long run may be the reason it will not heat well.

The thermal fuse is a small safety part. When exhaust heat spikes, it blows and cuts the heat or the whole dryer. It cannot be reset. Mr. Appliance says not to bypass safety devices such as thermal fuses, and we agree (Mr. Appliance).

How to test it. Unplug the dryer. Set a multimeter to ohms and touch both fuse terminals. A good fuse reads close to zero. A blown one reads open.

Cost. $80 to $180 with a pro, parts and labor. DIY friendly if you are handy. Our thermal fuse replacement guide walks through it. A fuse that blew once will blow again if the vent is still clogged, so clean the vent in the same visit.

On an electric dryer, the element is a long metal coil that glows like a toaster. Over time it breaks, much like an old bulb filament. Signs are a tumbling drum, damp clothes after a full cycle, and sometimes a visible gap in the coil. Restricted airflow often overheats the coil and shortens its life.

How to test it. Unplug the dryer, remove the back or bottom panel, and check the element for continuity with the multimeter. Mr. Appliance lists a continuity check as the way to confirm a broken element. No reading means it is open and needs replacing.

Cost. This is the priciest fix at $150 to $280 for a pro. It is DIY friendly with moderate difficulty. Our heating element guide covers it step by step in about 45 to 90 minutes.

The thermostat or thermistor reads drum temperature and tells the heater when to turn on and off. When it fails, it usually fails cold. Mr. Appliance lists a worn cycling thermostat as one reason a dryer heats and then stops mid cycle.

How to test it. Same multimeter check as the fuse. If the thermal fuse and the element both test fine and the vent is clear, this is the next suspect.

Cost. $100 to $200 with a pro. DIY friendly, but a wrong guess gets expensive, so call a pro if you are not sure.

Gas dryers do not have an element. They light a burner. If you see the igniter glow but no flame ever appears, the valve coils are the classic failure. If the drum runs and there is no glow at all, the igniter is the likely culprit.

Cost. $120 to $230 with a pro. We suggest you leave gas work to a pro. Mr. Appliance warns against servicing gas parts without training and tools.

Every cause on that chart is under $300 with labor. That matters when you decide between fixing and replacing.

Most pages on this topic were written for places with snow and cold basements. Here are three Arizona reasons a dryer loses heat that those pages skip.

Dust storms and the outside hood. NOAA says one to three large dust storms move into the Phoenix area in a given year, with walls of dust up to 10,000 feet high and winds up to 60 mph (NOAA haboob page). On August 25, 2025, the National Weather Service reported visibility under a quarter mile and winds near 50 to 65 mph across the Phoenix metro (NWS Phoenix). That dust gets into hoods, mixes with lint and cakes inside the duct. After a big storm, go look at the hood. Our guide to cleaning a dryer vent in Arizona says to check it after every one.

Long roof runs. Many Arizona homes put the laundry in the middle of the house, so the duct climbs and exits through the roof. The Building Energy Codes Program says to use smooth metal duct no longer than 35 feet, including the equivalent length of bends (PNNL). Its guidance takes 5 feet off the allowance for each 90 degree bend. Two bends leave you 25 feet. Your dryer manual has its own chart and it controls. A roof run with extra bends and a rusted flap is exactly where lint piles up. In a Phoenix attic that heat also bakes the duct, so check seams for gaps.

Monsoon power flickers. The monsoon runs June 15 to September 30 (APS). Storms knock out power, and APS tells customers to unplug unnecessary appliances so electrical spikes do not hit them when power returns (APS storm prep). We suggest you also check the dryer breaker after any outage. A breaker that did not reset cleanly is a free fix that looks like a dead heater.

If your dryer is in a hot Tucson or Phoenix garage, airflow matters even more. The dryer is already pulling in very warm air, so a weak vent leaves it hotter inside. Our Phoenix repair page lists local companies if you want a pro.

Call a pro when the breaker keeps tripping, you smell burning, you have a gas dryer, or you have done the free checks and the parts tests and still have no heat. Also call if the cord or outlet looks burned. Do not use a dryer that smells like smoke. Unplug it.

Tell them the brand and model, whether it is gas or electric, and that the drum turns but there is no heat. Say what you already checked, such as the breaker, the vent and the lint screen. Ask for the price before they open the dryer. A $75 to $150 service call fee is normal in Arizona and usually applies toward the repair. Find a pro in our washer and dryer repair directory.

Repair it. Almost every no heat cause costs under $300 with labor. Mr. Appliance gives two rules. Replace if the repair is 50 percent or more of a new dryer, or if the dryer is over 15 years old and repairs keep coming.

InterNACHI puts the life of a clothes dryer at about 13 years (InterNACHI life expectancy chart). The same chart gives 20 years for a steel dryer vent and 5 years for a plastic one. That is another reason to use metal duct. A dryer under 10 years old with a $100 to $200 fix is a clear repair. At 13 years or more, weigh the price against a new machine.
