CRGR7900AS3 Frigidaire Dryer - Instructions

The repair actually was quite easy but diagnosing the problem was another story. I found out that the dryer would not buzz and vibrate , if I just ran the fluff cycle but no heat. As soon as heat applied, the slight buzzing and slight vibrating would occur after a few minutes. I knew it wasn't the drum bearing, the drum rollers, the rubbing collar on front of drum, idle arm, belt, etc - I had replaced all of them less than a year ago. Anything I found on the internet dealing with the motor was always geared around not running or slow starting or shutting down, loud buzzing, needing a push start to start, etc but that was not the case. So I figured it was the blower housing and ordered that part. However, once I had the machine apart the blower housing seemed to be just fine - nothing obvious, everything tight. The one issue I had was removing the plastic nut with the metal insert on the blower unit that attaches it to the motor shaft which just wouldn't bulge. So I said to myself, the h*ll with it, lets get a new motor, too and remove both parts together which btw, was very easy. So that is exactly what I did. Now with new motor in hand and new blower housing in hand, I easily removed the old motor still attached to the old blower housing together and replaced both which was very easy. Hooked everything back up and no more soft buzzing or slight vibration. Now back to the problem or my guess at this point. I noticed that the rubber mounting bushing in the back of the motor which is used to attached it to the dryer bracket was funking looking - kinda soft and a bit perished. So I am surmising that once heat was introduced, it was enough to soften that bushing enough to cause the slight buzzing and slight vibration but without the heat to soften the bushing a bit, it was quiet and steady. Just a guess but for anyone that has this issue with just heat but no issue with fluff (no heat) check out the condition of that rubber mounting bushing on the rear of the motor. No where on the internet was there any info concerning the symptoms I had and I was flying by the seat of my pants. So am taking the time to get this on record in case someone else has these symptoms and finds it.

**I'd already installed a new rear drum bearing assembly (very simple) and the issue continued. Further testing (running unit with the drum removed) indicated the blower assembly and/or motor was the source as the issue only occurred when the unit was under load. I ordered both parts as there was simply no way the original blower assembly was coming off the original motor.** Disconnected Power. Removed Top and Front of Dryer. Removed Drum. Disconnected Wiring Harness at Motor. Disconnected Blower Housing Temperature Sensor. Pried Open Clip Holding Motor to Mounting Bracket. Removed All Other Mounting Hardware. Removed Original Motor and Blower Assembly. Mated New Blower Housing to New Motor. Mated Assembly to Mounting Bracket. Reinstalled Clip Holding Motor to Mounting Bracket. Reconnected Wiring Harness at Motor. Reconnected Temperature Sensor to Blower Housing. Installed All Other Mounting Hardware. Reconnected Power. Checked Assembly Alignment. No Issues Noted. Disconnected Power. Reinstalled Drum and Front of Dryer. Reconnected Power. Checked Assembly Alignment While Under Load. No Issues Noted. Reinstalled Top of Dryer. Issue is Resolved. ** Thoroughly cleaned entire unit including under the baffle located at the rear of the drum. Amazing amount of baked on lint located there. Checked heating element (no issues) and cleaned lint trap assembly in door of unit. Another area with an amazing amount of baked on lint. Total for all parts needed was $236.91. Total time needed was about 3 hours. Parts arrived within one day of order. Unit operates 'as-new'.**

Unplug the unit. The top of the dryer is held down by 2 simple friction pins. By lifting the dryer top above it's front door panel the top will swing up. Prop the top up so you can reach down the front panel. There are 2 Phillips screws about 6 inches down on the dryers front panel. Remove the 2 screws, tip the front panel toward you it will slip off the dryer drum. Remove the 2 push on wires attached to the door switch. Gently lift the front panel off the 2 hinge points at the bottom and set it aside. The parts that your going to replace are the 2 solenoids on the burner assembly. The burner assembly is located on the lower left side of the dryer. Remove the 2 Philips screws that "clamp" the solenoids in place. Pull the 3 & 2 wire friction connectors off the solenoids. Lift the clamp off the top of the solenoids. Pick the 2 solenoids up off the valve assemble. Put the 2 new solenoids on the valve assembly push the wires back on, put the clamp back on and resemble the dryer. *Note: just to make a quick check on the continuity of the solenoids. I suspended the dryer drum so it could rotate without damaging it, put my clamp on amp probe on the 120v line to the solenoids the 3 wire one was good the 2 wire one was open.

watched video on replacing rear bearing.although rear bearing was not the part(s) i needed to replace, video instructed disassembly procedures to get to the drum glides. this was a very simple and easy to follow video. repair was a breezeand took roughly 25 minutes. the most time consuming segement of repair was vaccuuming out lint,that was 15 minutes. In future, as a preventative, i plan to remove front of machine to clean annually.
Thank you.

Took off front panel, removed drum and replaced parts listed. A bit tricky to keep small parts in place. However, masking tape helped. Best of all was the online diagram of how the parts were assembled. In addition, taking step by step phone pixs aided in replacing parts since there was some down time between diagnosis and installation.

Unpluged the dryer, took out the light assembly, unpluged the wires to the unit, replaced the old unit with new unit from Partselect.
Plugged dryer in, problem fixed.

Thanks, PARTSELECT.

That saved me about $50.00 YAHOO!!

spoke with repair person he indicated problem was not door switch but control board, prior to repair person arriving I receive the switch in the mail, I unplugged drier used a small edged screw driver to remove door light switch, removed three wire clips from the old switch, re connected the wires to new switch pushed the new switch into its location, closed the door light went out and the drier started and has ran just fine ever since, saved myself several hundred dollars or a new drier

Used nut driver to remove screw and cover from dryer cord terminal block, used screw driver to remove two screws securing old terminal block, cut dammaged wire and stripped wire back and crimped on new terminal connecter, replaced old terminal block with new one, replaced two screws, installed new cord, and replaced cover plate and screw.

Unplug, lift top, unplug 5 wires, remove 2 screws, pull dryer front away while supporting drum. Remove old glides, snap in new. Reverse disassembly procedure

i just put the knobs on very easily.

Motor replacement requires removing/releasing the top and front of the dryer, then removing the drum through the front of the dryer. The top is hinged at the rear and the front can be pried up. The front is held by two sheet metal screws that are accessible once the top is lifted up. Three screws hold the drum to the bearing at the rear of the drum. A small access door on the rear panel allows removal of the idler arm and its spring. You will need a socket drive with a short extension to remove the fan assembly from the motor at the front of the dryer, and it has a LEFT-HAND thread. The most difficult part of the replacement, once you figure out how to access everything, is getting the drum re-attached to the bearing at the rear of the drum. It can be hard to align the three screws, and once you have that done they need to be carefully tightened a few times after rotating the drum a few cycles, to get all the play out. Once the motor was replaced the dryer works like new.

unplug dryer. lift the top of the dryer up and back. Take the screws out holding the front panel on. One on each side. Disconnect wires from door open stop switch and take front panel off. Remove drive belt from around pulleys and lift drum up and forward out the front of the dryer. I had to replace the plastic and metal holder and the grounding ball also. Remove the shaft from the drum and put he new one on. Put the drum back in, wrap the belt around the drum and set drum in plastic holder. Then just reverse your steps. Fairly easy.

Dryer door would not close, part had broke and fallen in. Once part was received it took less than an minute to put the new one in and I was back in business.

thanks for making it easy to find the part needed. and the delivery was fast!

my motor was making noise i tried to replace the motor but could not get the blower wheel off the motor so i had to buy a blower and housing assy. also... now it works great...

Like the review of the guy who said "no story to tell. received knob and popped it on." I did not realize when I spoke to the Fridgedaire 1-800 number that I needed the model number; even though, I had the part number of the knob. When I came across your website, I entered the part number which was on the back of the knob and your website brought up the correct item I needed. I had seen the part on another website and your pricing was more than half off their price. Plus you shipped it directly to me two days later.

Thanks, fm
