Direct answer: An Electrolux dryer squeaking noise is usually coming from the drum support path, not the heater. Start by pinning down when the squeak happens: only with clothes, only at startup, once per drum turn, or all the way through the cycle.
Most likely: The most common causes are something rubbing in the drum, a worn dryer drum belt riding badly, a dry or failing dryer idler pulley, worn dryer drum rollers, or a dryer drum felt seal starting to drag.
A sharp chirp, bird-like squeak, or rubbery squeal usually gives you a better clue than people think. If the sound changes with load size or shows up once every revolution, that points you toward the drum and belt path fast. Reality check: a dryer can squeak for a while before it quits, but the noise usually gets more expensive if you ignore it. Common wrong move: spraying lubricant into the cabinet without confirming the source first.
Don’t start with: Don’t start by ordering a control board or tearing into the heater section. Squeaks are almost always a moving-parts or rubbing problem.
The dryer sounds mostly normal empty, but starts chirping or squealing with towels, jeans, or a full mixed load.
Start here: Start with load size, items caught at the drum edge, and a belt or idler pulley that slips under heavier drag.
The noise is strongest in the first few seconds, then may settle down or come and go.
Start here: Start with the belt path and dryer idler pulley. Startup squeal often means a dry pulley or belt drag.
You hear a repeating chirp that matches drum rotation instead of a nonstop squeal.
Start here: Start with the dryer drum rollers, drum felt seal, or something rubbing the drum in one spot.
The dryer runs, but the squeak stays steady and may get sharper as the machine warms up.
Start here: Start with worn support parts and lint buildup around the drum path. Heat can make a dry roller or seal noise more obvious.
A bra wire, zipper, drawstring end, coin, or lint wad can squeak or chirp as the drum turns, especially with mixed loads.
Quick check: Run the drum by hand with power off and look around the front drum lip and baffles for anything dragging.
A startup squeal or steady high-pitched chirp often comes from the pulley that keeps tension on the dryer drum belt.
Quick check: If the sound is strongest at startup and seems to come from low in the cabinet, the idler pulley moves up the list fast.
A roller with a worn spot or dry bearing can squeak once per turn at first, then become a rougher rumble later.
Quick check: A repeating squeak that matches drum rotation, especially under load, points toward the rear drum support rollers.
A felt seal that is worn, folded, or separating can make a rubbing squeak and may leave dark lint or scuff marks near the drum edge.
Quick check: Look for lint streaks, fabric snagging, or visible rubbing at the front or rear drum edge.
A lot of dryer squeaks are simple rubbing problems you can catch without opening the cabinet.
Next move: If you remove debris or a rubbing item and the squeak is gone, you likely caught the problem early. If the noise stays with an empty drum or clearly comes from inside the cabinet, move to airflow and load checks next.
What to conclude: If the sound changes a lot between empty and loaded, the belt path or drum support is more likely than a random loose object.
Poor airflow and heavy loads do not usually create the squeak by themselves, but they make support parts run hotter and noisier.
Next move: If the squeak drops off with a smaller load or after restoring airflow, keep using light loads until you inspect the support parts. If the squeak is still there regardless of load and vent condition, the problem is likely inside the dryer cabinet.
What to conclude: Heat and drag can make a weak idler pulley, belt, roller, or felt seal complain sooner, but they are usually not the root cause by themselves.
The timing of the noise tells you which moving part deserves attention first.
Next move: If one pattern clearly matches what you hear, you can inspect the right area first instead of replacing parts blindly. If the sound is hard to isolate or has turned into grinding, stop using the dryer until it is opened and inspected.
Once the outside checks are done, a visual inspection usually confirms the real cause quickly.
Next move: If one part feels rough, wobbly, glazed, or visibly worn, you have a supported repair path. If all support parts look good but the noise remains, stop and consider a professional diagnosis before going deeper into motor-related noise.
Once the bad part is identified, replacing the actual worn component is the clean fix.
A good result: A quiet test run with a normal load confirms you fixed the actual source instead of guessing.
If not: If the same squeak survives a confirmed support-part repair, the remaining suspect is usually deeper in the drive system and worth a pro inspection.
What to conclude: Most dryer squeaks end here with one worn support part replaced. If not, the problem is no longer the common easy-fix path.

Because the heat side can be fine while a moving support part is wearing out. A dryer idler pulley, dryer drum roller, belt, or felt seal can squeak for quite a while before drying performance changes.
Sometimes it is just an early wear noise, but it is not smart to ignore. If the squeak gets sharper, turns into grinding, smells hot, or starts scraping metal, stop using the dryer until it is inspected.
Usually no. On most dryers that is a temporary bandage at best, and it can attract lint or contaminate the belt path. Find the worn part instead of trying to silence it with spray lubricant.
A startup squeal or steady chirp often points to the dryer idler pulley. A squeak that repeats with drum rotation, especially once every turn, leans more toward a dryer drum roller or a drum seal rubbing in one spot.
Only if inspection supports it. Replace the dryer drum belt when it is glazed, frayed, cracked, or clearly slipping. If the belt looks good and the pulley or rollers feel rough, the belt is probably not the main problem.
Heavy loads put more drag on the drum and belt path. That extra strain often makes a weak idler pulley, worn roller, or tired belt speak up sooner.
