Blown fuse on Moffat range

Right hand 30 amp fuse does not blow when oven turned on.
Left hand 30 amp fuse blows when oven turned on.
Both top and bottom elements still work with left hand fuse blown but clock does not.
What is confusing is that both fuses are labeled with the zigzag elemnt sign.

    Yes but if I hade a manual I wouldn't need Fixya. What I really want to know is why one fuse blows when I turn the oven on and the other one doesn't blow. Particularly when both fuses appear to be labeled as oven elements.

  • Michael StLeigh Jan 26, 2009

    Ginko, thanks, so the left hand fuse has nothing to do with the oven elements, everything works except the clock. You are therefore suggesting that the defect on the power board or harness is some kind of short that is on the clock circuit, is that correct?

  • Michael StLeigh Jan 27, 2009

    Thanks Robert, are you suggesting that one of the elemnts has a short even though they both still heat up with one of the 30 amp fuses blown?

  • Michael StLeigh Jan 27, 2009

    yes Ginko understood the problem and has offered further assistance if needed.

, The fuse panel/control board is located behind the digital display in the front of the unit. Some drop in ranges are tricky getting into so be carefull when removing the face , there are screws under the display when opening the oven door look up and there may be a few more on the top side corners reveled when you pull the unit out 12" or so. there is a small glass fuse in the board some of these are not removable so if there is no digital display on your oven and your sure you have 240V to control board you will need to replace the entire control board. Hope this gets you there. Good luck let me know if you have anymore problems.

    CHANGE THE BULB

    Most likely the problem with your oven is a bad display board (aka clock). In order to fix the problem it has to be replaced.

    Temperature range 50 - 250°C (120 - 480°F). ... Oven light not illuminating. Blown bulb. Replace bulb. Slow recovery. Overloading of oven

You have a short in the wiring or the element has. the clock is probably wired to the same circuit as that element .... pull the element and examine the wiring... you should be able to lift up the lid to look under the elements ... look for burned or chaffed wiring

incidentally if you pull the back cover off ... there should be a wiring diagram inside... or it may be stuck right on the back cover of the stove.

The left hand fuse is the one that protects power boar, if it has blown then there is either a problem with wiring harness , or you need to replace pwer board.

Enter model number here to get schematics and part price for your model.

    Hi there, yes , either a short, or a bad timer control, or a bad voltage because of a contact.

    You need to check the timer control board, and look for blown components and short.

    If board is fine, check wiring harness.

    If short was at elements' wiring you would have blown other fuse.

    If you give me model number, I can try to find schematics for this model.

Hi
Left fuse is blowing because of shorting of mains wire with the element or any other component in the range,

Check for an electrical short by checking that there is NO continuity between any "phase in" line and the metal appliance body itself.

Check for the item failing (element, control etc) by using a
multimeter.

    Also, carry out a continuity and resistance check on the appliance.

    Check for an electrical short to the appliance.

OVEN CONTROLS AND OVEN DONT WORK. RANGE TOP WORKS FINE.


Hello,

We're having the same problem. Oven light works, but plug by oven light switch does not. I changed the screw in fuse (15 Amp) in the oven, although it was blown, it didn't fix the problem.
I will be checking the double breaker on the electric panel tonight, making sure it's getting the full 220v, and if that is good, I will be looking at checking and replacing the clock.
Hope this helps.

Can a bad voltage regulator cause the main 30 amp fuse to blow?


Usually a bad regulator will only cause problems with charging...
Sounds like you've got a short somewhere in the wiring...I'd start by checking the ignition switch wiring and the connections going into the fuse box.

I am looking for a fuse in my antique stove 1948 moffat


I have a Moffat of about this vintage. Are you saying you can't find where the fuses are? Mine are underneath the left-hand drawer - the drawer under the warming oven. I just pull the drawer out and I can see them.

Does a moffat oven need a 30amp cooker socket or is it ok on a 13amp plug


Unless your talking about one of those tiny, table top ovens, dont use a 13 amp socket / connection.

An electric oven must be connected via a 30 amp SUPPLY - the socket is just the connector at the end of the cable that runs from the fuse / breaker board. A 30 amp supply will use a much thicker cable capable of handing the higher currents.

Whilst a very basic oven may draw less than 13 amps current when operating in some modes, most will draw well in excess of this depending on what facilities they have, e.g. bake and grill at the same time, or maybe a combi-oven - one that can bake and microwave at the same time.

Gaggenau EB 194 Double Oven fuse blowing

Oven wont turn on


If your microwave oven doesn't seem to work at all, check these:
Fuses Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it.

Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work.

Blown Fuse


It's drawing too much power. Maybe a short in an amp. Do you have any warranty left? Double check to make sure you have the right fuse. You might also try a slow blow fuse so  you can turn it off right away as soon as the fuse starts to glow to help in diagnosing.

Oven fuse blows - Nothing works


try lifting the stove top assy and checking wires under main top, leading to the elements them selves??? if tis tripping and not allowing to reset its gotta be an obvious short. isit hard wired directly to stove or into a 220 cord and plug???id look again, perhaps remove entire back panel and have someone trip on the breaker you might see where it flashes as it trips off
