Whirlpool Dryer Not Heating: Proven Ways to Fix It Fast

Ever found yourself standing in front of your Whirlpool dryer not heating and wondering what went wrong? As an appliance repair expert, I’ve been there too. One evening, after a long day of fixing appliances, I tossed a load of laundry into my trusty Whirlpool dryer. 

An hour later, I expected warm, dry clothes, but they were as damp as when I put them in. It was quite a head-scratcher! Whether you have a gas or electric dryer, these steps will help you troubleshoot the problem. Let’s dive into some common reasons and simple fixes to get your dryer back to its warm, cozy self.

Common Causes for a Whirlpool Dryer Not Heating

So, your Whirlpool dryer is not heating? Don’t worry, we’ve all been there. There are a few common reasons why this might be happening. Let’s go through them together and see what’s going on with your dryer. Some of these fixes you can do yourself, but for others, you might need a pro.

Power Supply Issues (DIY)

1. Voltage Check: First, make sure your dryer is getting the right power. Electric dryers need 240 volts. Use a multimeter to check the outlet. Each live line should give 110-120 volts. If it’s a three-prong outlet, you should measure 220-240 volts between the live lines.
   • How to Use a Multimeter: Set the multimeter to the voltage setting. Insert the probes into the outlet slots. A reading of 220-240 volts between the live lines means your outlet is good. If not, you might need an electrician.
2. Power Cord: Inspect the power cord for any signs of damage. A damaged cord can stop your dryer from heating.
   • Replacement Tip: If the cord looks frayed or damaged, it’s best to replace it. You can find a replacement at any hardware store.

Clogged Vent (DIY)

1. Vent Cleaning: A clogged vent can stop your dryer from heating properly. Clean the lint screen and the entire vent path, including the outside vent flap. I remember cleaning mine and finding a bird’s nest in the outside vent – talk about a surprise!
   • Thorough Cleaning: Use a vent cleaning brush or a vacuum to remove lint from the vent tubing. The vent should be as straight and short as possible, ideally under 25 feet.
2. Ventilation Slots: Check the ventilation slots at the back of the dryer. Make sure they are clear of lint and dust.
   • DIY Tip: A quick vacuum can help clear these slots and improve airflow.

Heating Element Failure (DIY/Pro)

1. Testing the Heating Element: Use a multimeter to test the heating element for continuity. If it shows no continuity, it might need to be replaced. This can be a DIY fix if you’re comfortable with tools, but calling a pro can be a good idea too.
   • Step-by-Step: Remove the back panel of the dryer using a quarter-inch nut driver. Disconnect the wires from the heating element. Set the multimeter to the Ohms setting and touch the probes to the terminals. A reading of around 10 ohms indicates it’s good. No reading means it needs replacing.

Thermostat Issues (DIY)

1. High Limit Thermostat: Use a multimeter to check the high limit thermostat for zero ohms of resistance. If it reads zero, it’s good. Otherwise, it might need replacing.
   • Testing Tip: Remove one wire from the thermostat to avoid false readings. Touch the multimeter probes to the terminals to check for continuity.
2. Operating Thermostat: Similarly, check the operating thermostat located lower in the heating circuit.
   • Quick Check: Follow the same steps as the high limit thermostat to test the operating thermostat.

  (DIY)

1. Testing the Thermal Fuse: The thermal fuse is a safety device. If it’s blown, your dryer won’t heat. Use a multimeter to test it for continuity. If it’s bad, replacing it is an easy DIY fix.
   • Safety First: Always unplug the dryer before testing the thermal fuse. Remove the back panel, locate the fuse, and test it with a multimeter. Zero ohms means it’s good.

Timer and Control Board Issues (Pro)

1. Testing the Timer: If your dryer isn’t moving to the heating cycle, the timer might be faulty. This is usually a job for a pro because it can be tricky to test and replace.
   • Pro Tip: Look for large wires, usually black and red, on the back of the timer. Set the timer to a heating cycle and check for continuity between the appropriate terminals.
2. Control Board: If the control board isn’t working, it might not send power to the heating element. Diagnosing and fixing this often requires professional help.
   • Expert Help: If you suspect the control board, it’s best to call a technician. They can accurately diagnose and replace the control board.

Motor Centrifugal Switch (Pro)

1. Switch Check: This switch allows the dryer to heat once the motor is running. It’s difficult to test and rarely the problem, but if all else fails, a pro might need to check this component.
   • Pro Insight: This switch is deep within the motor, so it’s best left to professionals to check and replace if needed.

Troubleshooting a Whirlpool Dryer Not Heating

Here are some steps to troubleshoot your Whirlpool dryer not heating. We’ll find the problem together!
