My heater is making a very high pitch sound after 15mins. I suspect it is the coming from the 77707-0256 Air Blower Kit, Propane - 400LP Model bearing. Can you adivise how to remove and inspect? Is it posible to replace the bearing? Thanks!
Thank you for posting your question here on Fixya.com.
IS it only with the heater on? The only possible issue that causes heater to whistle is poor air flow during combustion. If it is the heater you'll need to look at any surrounding obstructions to clean air flow...things like bushes, grass, fencing...If the heater is off and the noise persists try to narrow it down to which motor is making the noise and repair the bearings. One last possibility would be a blower motor in the heater if it is an induced draft model. If your heater has a blower motor or two of them check them both to see which is failing and again look at getting the bearings replaced.
