Rinnai RHFE 1004fa making a horrible squealing noise

I have the Rinnai RHFE 1004fa. It is making a hideous squealing noise when the heat is blowing. The problem started as an intermittent squeal that wasn't nearly as loud. Now it is all the time when the heater is running and it is crazy loud. It's in my living room and it is driving me crazy. So crazy that I'd rather be cold. Here's a link to a video I took where you can hear it. Hold your ears! https://www.facebook.com/photo.php?v=3291994983847

SOURCE: Rinnai RHFE 1004F Error code 49

A 49 error code is caused by the pressure switch either not proving or a bad component. Check the hose attached from the plastic elbow located behind the heater going to a small square pressure switch found inside the heater. It may have come loose or a mouse may have taken a bite out of it. Also while you are behind the heater, pull off the hose that looks like a vacuum cleaner hose and run the heater with it unattached. If it runs, you have a blockage in the vent. If not, take a flashlight and go outside to the vent. Look down the center pipe for any obstructions. If it still does not work, you may need a new pressure switch.

While the front panel is off the heater, cycle the heater to attempt a start. You want to make sure the blower turns. If it does not, check the wire connections to it. You may be looking at a bad blower. If it is turning but still does not start, we are looking at a bad pressure switch.

Let me know what you find, I may have a switch or blower motor that you can purchase.

SOURCE: I'd like information on the reliability of Rinnai

Beside the filters in the back, no they don't require much. After 8 years of installing and servicing these units, I haven't found a unit yet that was running faulty due to lack of service. Would recommend a cleaning of the burners about every 3-5 years. Rinnai recommends cleaning the unit with compressed air through the front grate annually...but that doesn't require disassembly

Hi Doug,
I have not seen this problem and my suggestion would be to look at the bearings in the combustion fan motor.
This motor is located in the lower right hand side of the unit and can be seen once the front cover is removed.
You can watch and listen when the unit starts up from a cold start and this should confirm where the noise is coming from.
This part is not easily removed and I suggest an experienced service person should perform the removal and replacement if this part is causing the noise issue.
if this does not help please contact me again
Good luck

Rinnai makes a good product and certainly if it's making a noise, it should be serviced and checked by an authorized Rinnai service technician. That way, you can determine whether the cost of repair ot ways the purchase of a new one. A good rule of thumb i, if the cost exceed 50% of the cost of a new one, it's wiser to purchase a new one. Which will have higher technology and a new warranty.

Using the rinnie as a major heating source for an older home


The smaller the vent the better. A Rinnai may heat an area just fine but a whole house is pushing it.
