The service manual (here) has a lot of operating information in it.

Also, we have a similar model's owner's manual here, and it may be close enough to help you.

I tried the ICE60705 number and it did not cross http://www.appliancepartspros.com/partsearch/modelsearch.aspx?model=IEC60705

Is that a serial number by chance?

To do any of the below the chassis cover must be removed.

To perform a diode resistance check you must first ground the high voltage capacitor several times to avoid a nasty shock.

To check the Diode you have to disconnect one side if the diode before reading resistance. Read the Diode on R X 1000 and then reverse the meter leads is should only ONE way. IF it reads both directions or not at all then it has failed.

To check the HV Capacitor (After grounding) you reverse the leads repeatedlyand watch for a momentary jump on an analog meter EACH time the leads are reversed. No jump of the meter needle = bad Capacitor.

Diodes can be found here:

I know that this is an 850W free standing Microwave. I just can recall the model number from memory.

If you find either one of the 2 parts bad I recommend contacting a LOCAL appliance parts center with parts in hand for the simple fact the model number is not crossing.

Just make sure they failed per directions above before replacement.

Thanks again for choosing FixYa.

P.s. If the above parts check out good then that leaves the door switch or the magnetron as possible failures. If the Magnetron has failed you may want to evaluate repair vs total unit replacement cost of the microwave.

hi, running it with nothing in it will cause it no harm, the only object that will cause it any harm is if you place anything metalic inside it whilst it is switched on.

to clean a microwave most people place a bowl of clean water inside and put the microwave on high for 5 to 10 min doing this breaks up any grime stuck inside the microwave making it easier to wipe off, you can also put a wet cloth in a bowl and switch it on doing this does the same as a bowl of water.

so the only thing that can cause damage is anything with metal in it this will cause it to short out.

hope that has been some help to you

Most of these over the range models come already set up for unvented operation. That is, set up for use with no outside vent. The oven will filter air through the a charcoal filter inside the upper grill and the vent covers underneath. If you ever wish to change the operation to allow the unit to vent outdoors, you need to change the direction of the blower fan assemby inside the top of the microwave oven. These instructions should be listed in the installation manual that comes with your oven.

You didn't mention your brand or model, but since you posted this under the Sharp R-1480 category, I'll take the chance that's what you have.

WE have the full R-1480 service manual and have uploaded it to our site here to help you.
If that's not your model, feel free to contact me at [email protected] and I may have the manual and can link you to it.

You can find links to helpful exploded view diagrams and part ordering help here.

I recommend that you bookmark that link to your favorites.Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the previously hidden screw(s) you need to remove.

Or you can watch a YouTube video (not a video I made) that demonstrates how it's done.

Hi,

I have the GE JVM1490 Profile Spacemaker. Dr. Ripken's solution works for this oven. You need to remove the front vents, and lift up the plate covering the fan. The bulb housing is bright stainless steel and hinges up and out. The bulb part is the same as the underneath bulb. Unplug the oven before you replace the bulb or you can fry yourself or the control board. nuff said. P.S. I called GE and they said this had to be done by a tech. I guess they are scared of getting sued. -1 for them.

First and foremost, unplug the oven or disconnect it from the AC supply. Failure to do so can damage you or your microwave.

On some models, there is an access panel in the rear or inside the cavity (cooking chamber) held in place with a screw. Apparently yours does not have either of these.

For other models, you do have to remove the outer wrapper / cover.
Quoting my own text "doorsw.txt", here's how:

Remove all of the screws from the side and back of the outer wrapper / cover of the microwave. There are usually four on the rear edges and two on the bottom of the edges on each side of the cover.

The cover then should be slid slightly backward then up from the rear and it will slide off.

You may have to pat down on the sides to loosen it first. I use firm and simultaneous open-palmed slaps on both sides near the front, then pull it up and off.

When putting it back on, be careful that the inside front edges of the cover catch properly in the slots in the chassis.

Once the cover is off, be careful of sharp edges on the metal inside.

Also, do not come into contact with any exposed connections or wiring, since there may possibly be a charge remaining in the high-voltage capacitor.

A zap from this charge can be painful, and it can cause you to hurt yourself on those sharp edges when the old reflexes move you abruptly!

If you are not ok yet i can still assist you more.

Take care.

I'm curious how you expect anyone to help you with the information you provided.

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

Since you posted this under the R-1480 category, maybe yours is an R-1480? If so, here is the service manual.

We have manuals for several models which you can download free, but we would need to know which model you have.

On the chance that yours is an R-1480 (since that's what you posted under) we have a similar one here.

Otherwise, feel free to contact me directly for free assistance.

Yes, but if it's not a US or Canadian model, it will run double the rate due to shipping costs. See details here.

hello,
what this means is that the timing of your oven have been program on 59 seconds mistakenly

what you need to do to correct this problem is that you will have to reprogram the timing by resetting the time program on it by clicking on the setting button and type in the new timer with this the problem is solve

Good luck and thanks for using fixya.

It may be a door switch problem (see this file) or a stuck fan relay on the control circuit board, which we can repair for $39.95 in most cases.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.
