20 Most Recent Hotpoint RVM1435 Microwave Oven Questions & Answers


The Emerson MW8999SB 0.9 cu. ft. 900 watt Microwave Oven is relatively compact, and certainly inexpensive, but doesn't skimp on functionality. We were surprised at all the options you get with this little microwave. It's only 20 inches wide, 11.3 inches high and 16.1 inches deep yet. The interior can still accommodate a regular size dinner plate or small (10-inch-square or round) casserole. Plus, there are 10 power levels, eight one-touch function buttons, six Express Cook settings, timed and automatic defrost options, and a rotating glass turntable to circulate the food for more even cooking.

We were very pleased with the performance of the Emerson MW8999SB. It did a fine job heating water for tea, cooking a couple of baked potatoes, reheating leftovers and steaming fresh vegetables. Even the automatic defrost proved surprisingly efficient, letting you enter the weight of the item(s) to be defrosted (4-100 ounces) for easy operation. Chicken breasts were almost fully defrosted after one cycle. We needed to stop and separate the food pieces to finish the defrost cycle.

The unit is styled mainly in black but has stainless steel trim around the door and control panel. The smooth touchpad control panel is attractive and easy to wipe clean. We loved the one-touch Express Cook buttons, which let you activate the unit at 100 percent power for 1-6 minutes, by pressing the corresponding number pad. We also appreciated extra touches such as the Start/+30 sec. button, which can be used to start the oven or add an extra 30 seconds each time it is depressed.

It's hard to go wrong when the functions are so simple. The only tricky part was identifying certain codes used on the display screen. When changing the power level, for instance, PL10 is displayed on the screen. Pressing the button additional times lets you toggle through the different levels. Likewise, the Auto Cook settings may need to be pressed multiple times to obtain the correct weight or portion for the food being cooked.

We were amazed that a machine costing so little also offered two-stage cooking, which lets you start cooking (or defrosting) on one setting and finish on another. All in all, the Emerson MW8999SB is an excellent value.


Pros: Touchpad controls, eight one-touch function buttons, six Express Cook settings, two-stage coking option
Cons: Limited interior capacity can only accommodate dishes up to 10 inches, no sensor

The main controller board, or one of the power supplies has failed and require to be replaced.

You should take the microwave oven in for an estimate. I strongly suggest to not service this type of appliance yourself unless you are trained and experienced in microwave oven service.

There are many safety issues when servicing microwave ovens.

Hi Kerry,
"PF" is power falure if you didn't aready know this. It sounds to me like the coolig fan might be running slow or there is blocked or restricted air flow through the unit. This cooling fan is only for the HV transformer and magnetron. Sometimes you may get air flow around the door but this is incidental. The PF tells me that the power is being interrupted either at the power source (wall outlet or circuit breaker) or the magnetron TCO is cutting out. It also could be a bad magnetron running too hot. As far as the steam goes, I usually just leave the door open on my microwave for 10 or 15 minutes to let the condensation evaporate.

Cubic square feet is determined by multiplying length (depth) X width
X height. Example= 2X2X2 = 8 cubic feet. A typical countertop microwave is going to be 1.1 to 1.6 cubic feet of oven capacity.

This could be very dangerous.

I would first call your electric company and ask if they have any problems with their lines, etc. We recently had this problem at our home and it was in their circuits.

My mother in law had a similar problem and we caught it in time. In her house, several outlets showed extremely low voltage and the others showed extremely high voltage.

It turned out to be a bad neutral connection on the line going from the pole to the house. The electric company fixed it at no charge.

Also, you or someone you know should measure the voltages coming out of your outlets, or call an electrician right away.

You may have a loose circuit breaker or a bad connection somewhere your electrical panel or elsewhere in your neutral line.

This can lead to destruction of your appliances or even a fire, so please don't delay.

We're happy to help and we appreciate your thoughtful rating of our answer.
