The 1971 combo Hotpoint/GE range
The combo Hotpoint Range-Microwave here was bought in late 1971, installed early 1972. GE had the sister model too. These units have a lower regular oven and upper regular oven; plus 4 electric stove burners, one of which is a supermatic control. The 1971 combo Hotpoint/GE range has in the lower oven also an electronic oven running at the old lower 915 MHz frequency. Little tabletop units today run at 2.45 GHZ. Ours listed for about 1150 in 1971 and we paid about 850 to 900 bucks. The patent plate is 18.1KW.
The Hotpoint Range is a RHV886 ; the GE a Versatronic J896 Range
These are heavy ranges, 430 Lbs and the patent plate input is 18.4 Kilowatts, ie 80 Amps at 230 volts.
We got about say 10 good years out of the lower microwave; and about 15 until nobody could fix the magnetron anymore without totally going broke. For its era it was star trek. For a repair guy, a nightmare once something got too old. Having that microwave emitter in a heated regular oven was basically challenging, not the hallmark of something to last decades.
The lower "regular" oven lasted until Katrina; the relay behind it must be crudded up. The beast has no been pulled out since the flood I just use the stove and top oven. The conventional part of the lower oven is like a self cleaning oven of that era, there is drive relay behind the lower oven.
If anybody has a schematic for a HRV886 or J896 please post it; one the last persons who serviced the range walked off with the schematic inside; it is in a pocket behind the top right dials and clock etc.
