RR-1  (1967)

Here's what I know... The RR-1 has an electromagnet for the magnetron and weighs in at 90lbs according to Amana service literature. These units have two buttons- START (blue) and LIGHT (green). Also, the timers are additive so you can get 5 + 25 min total. The 5 minute dial is on the bottom, while the 25 min dial is on the top. RR-1's have a matte chrome finish along the top and bottom horizontal recesses of the front.

RR-2  (1968)

Essentially an RR-1 with the addition of a STOP button. The timers are still additive but the 25min timer has been bumped to 30min. Upper and lower timers swap locations where they will stay through the 4D series. The front is now entirely bright chrome. The perforated door screen continues to lack clear plastic panels on either side, making splatter cleanup difficult. RR-2's still lack an end of cycle chime/buzzer.

Damaged 3H Panel

in Collection

This is all I've got from a half destroyed RR-3H. "Cooking" logos have been added to each of the timer dials. Whereas model 1 and 2's allowed one to open the door (to stop the machine), the 3H includes a sliding LOCK lever at the top of the control panel. I'm unsure how long the 3 series was offered, but it must not have been long.

RR-3 Does such a beast exist?

RR-4 The 4 loses the LOCK slider. Perm magnet machine? The LIGHT button is no longer blue, but white.

RR-4D (D for Auto Defrost) According to my records, the 4D was released in 1974, and the 4DW in '75. The documentation I've seen for the 4DW claims it has an air-driven stirrer. Up until this point, all the RR's had motor driven stirrers. The defrost function of the 4D is very distinctive, when activated a loud solenoid/relay clunks on and off every so many seconds. The 4D is in the collection.

This particular model is in perfect condition with the original instruction manual, also mint!

RR-4DW After August 7th 1974, the gov't mandated that all microwave ovens have secondary lock circuits so that if the first interlocks were bypassed or failed, the oven would not operate. The 4DW adds a board with two protective fuses (one thermal) to disable the machine if the interlocks fail.

Note: The 4D & 4DW models must have proved very popular as there are quite a few of these still going strong in kitchens today.

RR-5B  Now when I got into this game, I said I was going to stick to the Touchmatic style Radars' and pass up the Cookmatics. Of course, when I got a tip from a friend about some Amana being placed at the curb, I had to check it out. Nowhere does it say Cookmatic, and in fact it has a block off plate where a Cookmatic slider would go, decorated with "scrollwork". It was a pure mess but cleaned up nicely, and works as well. Date of 1981. Includes end of cycle bell, but no COOK light. RR references indicate a COOK light on Canadian 5Bs only, perhaps to satisfy Canadian regulations?

5B's act like 7's in that if START is pressed without a time set, a circuit prevents operation for 5 minutes.

RR-6W  Hey, I like it. Lots of chrome, digital controls, and a neat egg timer function. Punch in your desired time interval, hit the Timer button and the display counts down to 0, followed by a pleasing tone very similar to the '84 unit below. The '81 has a very loud, unmistakable beeeep. Machine is in collection.   See below for internals and repair info-

RR-6 also an Amana model but the differences are not yet clear......possibly the non-secondary interlock version of the Touchmatic.

RR-7A The Cookmatic Series featuring a 5 minute timer, a 30 minute timer and a Cookmatic slider that controls cooking on-time from 10-100% each sec. via an electronic variable power control module. Circa 1979. Similar appearance to the 5B.
RR-7BET is the 50Hz version of the RR-7.
RR-7/7A Conversion According to Amana literature, there was a conversion panel made available July 1983 that replaces the lower timer with a power level knob (Percent Timer) and eliminates the Cookmatic slider. It provides the same functionality, but the Cookmatic control is internally motor-driven rather than electronic. Reliability issues?

RR-7B The 7B appears to be equivalent to a 7A Conversion. It features a 30 min. timer on top and Cookmatic Percent Timer on bottom (10%-100% on-time). Circa '82.

Interestingly, if START is pushed before the timer is set, a safeguard will prevent operation for 5 minutes! This appears to be true of ALL RR-7s

RR-7DA I'd like to see one of these. It appears to be a 5B setup but has a COOK light and an internal surge relay to lessen power surges to the transformer and thus keep kitchen lights from dimming during defrost cycles.

RR-9TA The stealth looks of a 9T from February 1981. From the front, the only difference beteween this and a 9T appears to be the control panel border- The TA having a flat chrome surround, the T having a painted border and ridge- Check these pics for the minor difference-  9T border  9TA border

However, some TA's have significant internal differences- this TA has been cheapened up. No ribbon cables or connectors to the faceplate, cheap PCB material, protective housing made of tin rather than heavy aluminum that doubled as a heatsink. And a whole mess of generic discrete components. It's more like a Yorx stereo in here than anything else.

Note the added PCB that turns the interior light on whenever the oven is running. Does not appear to be a factory piece.
From the exterior, the LEDs used behind the Cook/Defrost/Temp Ctrl, etc. buttons are the more common 5mm units rather than the 3mm LEDs. This TA beeps sharply if you tap Cook/Defrost/Temp Ctrl without entering a time. I have a report from another TA owner that his does not beep.

RRH-10  Very Interesting... an RR-10A in disguise. This machine was probably built during the transitional phase to the new styling. The date is Dec 1978. Click for a close up of the Heritage badge.

RRL-10A  This is the Touchmatic II version of the RRL line. (See RRL-9TA) Still featuring an LED display and a lot of quality. Build date of January 1980.

RR-700 Built-In  An interesting RR-700 designed to be built into a wall cabinet. The above-control panel exhaust port has been blocked with an Amana badge and sheetmetal unique to this model exhausts out the top.  More interesting, the door swings to the side and has the interlock built into the 'detented' handle. And yet, it's still marked RR-700 like the countertop units, despite being exclusively different. Sep '85.
