My fridigidaire model # cer3600as1 squeals when running. what is the problem?

What model is it? The answer is probably both. Every machine I've worked on has a motor with a belt that drives a pulley that turns the tub held in place by bearings. Your squeal could certainly be caused by a bad belt. If the belt looks bad change it. If it looks okay, try a squirt of belt dressing, if the squeal disappears change the belt. If it is a front loader open the loading door, put one hand just inside the tub at the top (like a waiter carring a tray shoulder high with one hand) and LIGHTLY push upwards then drop your hand a little then push upwards etc., etc. If the whole tub moves solidly you are okay, but if you feel a wiggle or a slight space in the jump (man this is harder to explain than i thought it would be) then your bearings may need attention. I doubt it is your bearings causing the squeal though. Does it squeal through entire spin cycle, or just at the beginning?

The power vent motor squeals when burner is activated?
See if you can oil the power vent motor.

If the water heater squeals when water is turned on, then remove heat trap nipples and inserts and install di-electric nipples from water heater department local home store.

You will need to replace the heater element with this replacement part.

INLET VALVE STUCK. REPLACE INLET VALVE. CONFIRM BY SHUTTING WATER VALVE OFF TO MACHINE, IF NO WATER ENTERS TUB WHEN OFF AT THE SUPPLY THEN INLET VALVE IS STUCK OPEN.

Likely the agitator ears are broken - or clutch is frozen.

Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question.

i don't think it is dangerous but it could be water minerals that was not filtered by your filter. sediments that is in the water that have settled at the lower part of the tubing.. if you can replace the coils of tubing then it would be much better.

tnx 4 using fixya,
