    Question Jenn Air Wall Oven installation

    Our 20 yo Whirlpool oven has finally died. We just ordered a Jenn Air double wall oven and I'm trying to decide if the installation is a do it yourself project or if I should pay the $269 for installation. I am fairly competent with basic electrical work (wired my basement refinishing project myself), but don't have any special tools. From what I've been able to read, it's a pretty basic connection process. Do I need any special tools, like a crimper of some sort to make the connections? I haven't taken the old oven out yet to look at the existing connections. It's on a 60A circuit, so I don't have to replace any wire. Any advice would be appreciated.

    Hi,

    No model# posted but JennAir has many of the install and manuals available on thier web site if you need to have a peek....they will also be packed in the new oven.

    269.00 *sounds* a bit high to me...JMO!!...but 2 people is best for a double oven to "pop" it in place!!

    Do I need any special tools, like a crimper of some sort to make the connections?
    Nope, most are marrette style connections inside a small junction box.

    Certainly -sounds- like you should have no problems hooking up the electrical for the new oven...esp if you can read and follow the instructions/tips that come with the oven

    Jeff,
    It's the JJW9630D. I've read the manual online for installation and it doesn't look too intimidating. The only question I really have now is the wire connections. I've read some posts that refer to crimping the connections, but it sounds like a standard wirenut of some form (not sure what a "marrette" type is) is used. As far as I can tell, it's only three wires to hookup. The price I was quoted was from Home Depot and included the removal of the old stove (but not disposal). My son and I are game for the challenge. Thanks for the info.

    Hi,

    not sure what a "marrette" type is


    Extra large wire connector with spring insert

    If you get a chance, let us know how the job went

    Smile Success

    My wife is busily learning how to use her new oven and cooktop. Got both installed and connected this morning and they're working like a champ. Thanks for the info. Couple of questions...the oven is on a 50A breaker, the cooktop on a 30A. According to the faceplate data, they call for a 60A and 40A respectively. (The existing supply wire is 8ga (oven) and 10ga (cooktop) aluminum so it could handle the bigger breakers. I used the proper cu-al connectors and anti-oxide paste) I turned both units on with the max power draw and neither breaker blew. Is there a safety issue I should be aware of, or can I hold what I have with breakers? The leads off both devices appear to be 10ga. Thanks for any insight.

    Hi,

    the oven is on a 50A breaker, the cooktop on a 30A.
    That is what the most common ones we install require.

    K.W. RATING ON SERIAL PLATE
    a 0 - 4.8
    b 4.9 - 6.9
    c 7.0 - 9.9
    d 10.0 - 11.9
    e 12.0 - 14.9
    RECOMMENDED MINIMUM CIRCUIT PROTECTION IN AMPERS
    a 20
    b 30
    c 40
    d 50
    e 60
    WIRE SIZE (AWG)
    a 12
    b 10
    c 8
    d 8
    e 6

    Match the letters.

    I turned both units on with the max power draw and neither breaker blew
    That sounds good so far!!

    Question

    I spoke too soon. My oven is popping the breaker when both the top and bottom are turned on. Here's my question. My supply wire from the 50A breaker is 8ga. The wire harness that connects from the junction box (using wirenuts) to the oven (using a screw terminal block) is 10ga. According to the charts, I need 6 ga for the 60A breaker. However, using the factory-supplied harness, this circuit will have a combo of 10 and 6ga wire. Can I install a 60A breaker without changing out the supply wire to 6ga? Why does the manufacturer call for a 60A breaker that requires 6ga wire, but then use 10ga wire on the connecting harness that the 6ga wire is connected to? I'm confused and don't want to do something that is unsafe, but can't figure this one out. Thanks for any clarification on this.

    Hi,

    Post the KWrating off of the model/serial tag and we will get WG's opinion. The wire between the house connection and the appliance always seems to be smaller, chances are for ease of installing behind the oven is one reason.

    The upper oven is rated at 7.2KW, and the lower is rated at 5.4 KW for 12.6 KW total. This falls into the 60A breaker range, but the harness wire is definitely not 6GA. WG, any insight into this? Thanks.

    I forgot, it's the Jenn Air 9630DD, double convection oven.
