Understanding the Problem
Overview: The Kenmore dryer model 796.91073310 (a common front-load electric/gas Kenmore dryer variant) can show several routine problems as it ages: not heating, not tumbling, long dry times, loud squeaks or thumps, and not starting. Below are step-by-step diagnostic and repair instructions for the most frequent faults. 1) Dryer won’t heat (or takes very long to dry) 1. Verify basics: make sure the dryer is getting full power — check the house breaker for the dryer and ensure the plug is fully seated. Electric dryers usually need 240V (two hot legs); gas dryers need 120V for controls and a working gas supply/pilot/igniter. 2. Clean the vent and lint screen: restricted airflow is the #1 cause of long dry times and overheating. Disconnect the vent and run the dryer (briefly) to see if airflow is strong. 3. Check the thermal fuse: locate the thermal fuse on the blower housing or exhaust duct. Unplug dryer, remove panels, and test the thermal fuse with a multimeter for continuity. If blown (no continuity), replace it. 4. Test the heating element (electric models): inspect the element for visible breaks and test continuity across the element windings with a multimeter. Replace if open or shorted to ground. 5. Check thermostats and high-limit cutouts: test cycling thermostat and high-limit thermostats for continuity. Replace if open when cold. 6. On gas models: verify the igniter and gas valve coils. If the igniter does not glow or the gas valve coils have no continuity, replace faulty parts. 2) Dryer won’t tumble or motor hums 1. Confirm the dryer powers on: if lights/controls work but drum doesn’t turn, try to turn the drum by hand. If drum is stuck, proceed. 2. Inspect the drive belt: remove the front/top to access the drum and belt. If the belt is broken, replace it. 3. Check the motor: if the belt is intact but motor hums and doesn’t start, test motor windings and centrifugal switch where accessible. Replace the motor if seized or failed. 4. Inspect idler pulley and rollers: worn or seized rollers/idler can stop the drum or make the motor struggle. Replace worn rollers and idler. 3) Loud noise, squealing, thumping 1. Remove the drum and inspect drum rollers, rear drum bearing, idler pulley, and glides. Worn or flat spots cause squeal or thump. 2. Replace any worn rollers, bearings, or glides. Lubrication is not typically recommended — replace the worn part. 3. Check foreign objects trapped between drum and cabinet (coins, buttons) and remove. 4) Dryer won’t start or stops mid-cycle 1. Verify door switch: test door switch for continuity when door is closed. Replace if defective. 2. Check start switch and control board/timer: test for continuity and correct voltages. Replace faulty start switch or control module. 3. Inspect thermal cutouts / high limit thermostats which can open and cut power mid-cycle. Basic repair steps (example: replace thermal fuse) 1. Unplug the dryer (or turn off the gas supply if gas model) and move dryer away from the wall. 2. Remove the required panel(s) to access the blower housing/thermal fuse (commonly rear or front lower access). Consult your model's service sheet for exact locations. 3. Take a photo of wiring before disconnecting. Remove the wires from the fuse and unfasten the fuse from the housing. 4. Install new fuse, reconnect wires, reassemble panels, restore power and test the dryer. Basic repair steps (example: replace belt) 1. Unplug dryer and remove top or front panel to gain drum access. 2. Remove the drum from the cabinet (note orientation) and loop the new belt around the drum according to routing (idler pulley and motor shaft orientation). 3. Reinstall drum, ensure belt is on motor pulley and idler, rotate drum by hand to confirm smooth operation, reassemble and test. Safety note: Always unplug the dryer (or shut off gas and electrical breakers) before disassembly. Use proper tools, keep lint away from your work area, and if you’re uncertain about gas valve or electrical testing, hire a qualified technician. Some replacement tasks (gas valve coils, high-voltage checks) require care and knowledge of working with gas and 240V circuits.
Common Symptoms
No heat or very long drying times; drum won’t turn or motor hums; loud squealing or thumping during operation; dryer won’t start or stops mid-cycle.
Common Causes
- Clogged vent or lint buildup restricting airflow
- Failed thermal fuse, heating element (electric) or igniter/gas valve (gas)
- Worn drive belt, motor failure, idler pulley or drum rollers
- Faulty door switch, start switch, or control/timer module

Helpful Repair Tip
Before replacing parts, test the thermal fuse and heating element for continuity with a multimeter — a blown thermal fuse or an open element are the most common causes of 'no heat' in these Kenmore dryers.
Frequently Asked Questions
How do I find the exact replacement part numbers for my Kenmore 796.91073310 dryer?
Locate the model and serial tag (usually inside the door opening, on the door frame, or on the back panel). Use that model number on part lookup sites or the manufacturer’s parts diagram to find exact part numbers. If unsure, take a photo of the tag and the part and verify with a retailer or authorized parts dealer.
Can I clean the vent instead of replacing parts if my dryer isn’t heating properly?
Yes — always clean the lint screen and vent first. Restricted airflow often causes poor drying performance and can trip thermal safeties. If cleaning fixes the problem, no part replacement is needed. If the dryer still won’t heat after cleaning, proceed to test the thermal fuse and heating components.
