PLFU1777DS0 Frigidaire Freezer - Instructions

I replaced the timer and the defrost thermostat. The defrost thermostat replacement was almost exactly like the training video here. The old part attached slightly differently. The most time consuming part was thawing out the heat exchanger, which was completely covered with ice, inside and out.

Compared to the training video, the timer took more work given its location. It was low to the ground and a bit difficult to get at around the other wires and parts. However, the new part fit perfectly. I just unplugged and unscrewed the old part then reversed those steps with the new one.

Removed the old defrost timer by removing 4 screws on the holding bracket. Disconnected the wire harness. Reconnected the wire harness to the new part. Installed the new part with 2 screws on the top of the molded bracket. I am a 67 year old woman... easy-peasy. (the defost timer is located in the bottom left rear of the freezer.

I first replaced the defrost timer about a week prior and it did not correct the problem. I then ordered the thermostat from partselect and within 15 minutes had the part installed. My refridgerator has been running correctly for a couple weeks.

I worked for GM as a Frigidaire Tech, before starting my own business. I have retired now.
I took the three screws off the back of the bracket holding the motor. Disconected wire harness and pulled out the motor. Reverse to install. servantoftheking@hughes.net

A little difficult getting out due to restricted space, I took off the fan blade, that gave extra working room. Then it went well going back together,and it all worked as advertised. Thanks. p

I remove the old fan by pushing it off the spindle toward the evaporator and put the new one on by holding it on the right side and guiding it on the spindle from the left side, very easy task

Removed existing part, tested it, found it to be defective. OrderEd a new one and replaced the existing one.

Removed shelves ,removed panel on interior back wall with Philips screwdriver ,unplugged wire terminals slid thermostat off coil ,then reversed process to complete installation.

Both end caps were missing on the door side bottom metal shelf. succesfully installed no tools needed

Replaced thermostat and it fixed the problem. Freezer comes on and turns off automatically and regulates internal temperature around 2-5 degrees.
The hardest part was extending the coiled probe tubing and forming it to fit into clamp without kinking it.

I removed the screws and replace the broken slide with the new slide. Put the basket drawer back on the track and it now stays in place and can easily be used once again.

Received fan blade part took about 5 min to install and running great.

I changed the cooling control

It went exactly like your on line video. It took longer to defrost the freeze than it did to make the parts change out.

The timer in this older unit is clearly exposed at the back of the freezer underneath the freezer compartment. It is attached with two Phillips head screws. After the screws are removed, the timer can be unplugged and the new one plugged in. The new timer has an extra flange to allow it to be used on more than one model of freezer. In order to mount the timer in this unit, you have to remove the extra flange by carefully cutting it away from the timer body, in similar fashion to what's depicted in the online video. This will allow you to mount the new timer to the mounting plate using the two screws from the old timer.
