RT18HDXDN03 Roper Refrigerator - Instructions

Was told capacitor was problem 90% of the time.Capacior was not the problem.Bad start relay.

Simple to unscrew and replace parts

I just replaced my defrost thermostat after using the place-in-ice-water method, and I think it may not have been necessary. My timeline: my fridge was not getting cold enough. I realized it the day before going on a trip. I vacuumed the (very dusty) coils at the bottom, and the next morning the fridge seemed colder, but I thought I should order parts just in case. I ordered a heater and a thermostat. The fridge seemed to be operating normally when I returned from my trip, but I had the parts, so I thought I'd go ahead and dismantle the freezer and test the existing parts. My intention was to return both parts if the old ones passed the tests. I opened up the back of the freezer and there was no ice on the fins. I thought, great, the existing heater works! I cut out the thermostat, placed it in ice water, and didn't get continuity. So I decided to go ahead and put in the new thermostat. Because I'm not experienced with using a multimeter, I thought I'd test the new thermostat to see how the test should work. To my surprise, the new thermostat also failed the test! Stumped, I thought I might as well install the new thermostat, since I had opened the package and couldn't return it.
Further internet research suggests the place-in-ice-water method of testing is not adequate. One YouTube video by Parts Dr says to place the part in a working freezer. I froze my old thermostat and tested it; still no continuity. This thermostat may not be typical, though. The video discussed the temperature ratings on thermostats. The temperature rating on both (old and new) thermostats is L8.9-16.7C. That converts to 48-63 degrees fahrenheit, which obviously are not freezing temperatures. I'm not convinced I needed a new thermostat, but I trusted the videos I consulted earlier.
I cleaned the fridge thoroughly, so at least now I have a nice clean fridge to show for my efforts.

We looked up the problem online with the model number of the refrigerator. We ordered the part and followed the video installation that was sent with the order and was found online prior to purchasing

inst said,"50 pct of the time this calls for new capacitor," so we changed the capacitor. Same prob. It also said,"25 pct of the time it's the bi-metal thermostat" So we ordered it. We removed the plastic rear panel from inside the freezer comp. using small nut driver. Here we found much ICE surrounding the defrost unit, three inches thick. We thawed the whole mess. and the freezer has worked fine ever since. I think my habit of getting ice cubes from the inside container rather than from the ice cube dispenser, had kep t the freezer door open too much, interfering with the normal defrost cycle and allowing ice to build up over time so that it finally defeated the system. My new rule, "get ice cubes only from the front."

Eased the putty knife under the edge of the switch housing and pried it off. Pulled two wires off the old terminals and hooked them onto the new one and reinstalled into the refrigerator body.

Used the suggested problem list here to narrow down that the repair was most likely the run capacitor. Poped the new one in and I now have better control of my compartment ranges. I have a temperature gauge in each compartment. Check them every opening of the doors.

just insert

The first part I changed was the defrost timer but it did
not solve the problem, I replaced the bi-metal defrost sensor
and I have the same problem.

I can defrost by turning the clock manually and heater works.



























problem.

I followed the instructions on the video you provided with my order. Removed the freezer door and used the putty knife to loosen the old gasket and installed the new one. I'm a 77 year old female and if I can do it, so can you.

Inserted scraper behind gasket breaking it free from door, permitting a hand hold. While putting tension on gasket, slid scraper around door gently removing old gasket. Replaced gasket starting at top gradually working around door. No need to remove door.

Unplug refrigerator.
Pry switch out with putty knife
Remove two wires from switch
Attach wires to new switch
Push new switch into slot

Removed the old gasket and ran the hard edged lip into the opening behind the door liner. Concerned that the gasket does not seem to be attaching itself to the door well. First put it on the side of the refigerator and it would not adhere enough to support itself. While it closes it just doesn't seem to attach with the magnets in the gasket. These magnetic strips have a weak magnet side and a strong magnet side. I wonder if they put the wrong side facing the door when they assembled it. Counter this with a new gasket for an upright freezer which was twice the length and attached itself firmly to the side wall of the freezer and did not slide down.

Took out the old, cracked, crisper unit and removed the white trim piece on the handle so that we could re-use it on the new crisper unit (which, in spite of the $90+ price tag did not come with new trim). The whole thing took 3 minutes to do.

I just popped out the old switch with a flat head screwdriver. Removed the connections and then installed new switch by reversing steps. Popped in back in and the light went on.
