Q & As

Rated 4.2 out of 5 by 101 reviewers.
Rated 4 out of 5 by Straightforward product Fulfilling its purpose as its interior will take even my largest casserole dish. My last microwave had lasted over 30 years & was very heavy. This is much lighter. It is quite noisy but I have no problem hearing its beeps to tell me it has finished cooking. Simple to clean & operate. 10 May 2016
Rated 5 out of 5 by Love it Hope it lasts as long as my last Panasonic micro. Fan a bit noisy but one soon gets used to that. At least it's a strong fan and clears any moisture. 26 April 2016
Rated 1 out of 5 by Dreadful product - avoid it! Very poor quality product; specifically the door which is loose even when closed and poor quality plastic door latch. Added to that the door when closed does not always activate the door safety switch, and when not in use the light remains on and the turntables turns slowly. Returned to the store within the hour, and the same model on display was equally poor, so not a case of just getting a lemon on the day I would of expected much better from Panasonic Although the product should rate 0/5, I would rate JL 5/5 for their customer service, as always; no quibble return and refund, and even a gift voucher to say sorry for the inconvenience. Lesson learned is to look at the display models in store, but if you're after a very basic microwave with no gadgets that doesn't look like the control panel of Apollo 13 and with a turntable to take a large dinner plate, not many the (few) boxes. Will try the Samsung MS23F301TAS next. 02 April 2016
Rated 1 out of 5 by Didn't even work once !!! I picked up this new microwave today 28/3/2016 I read the instructions and tried to use it and it came up with error code H97 ??? I am really disappointed as I only upgraded due to my old one looking tired but that one was taken to the tip ready for this new one arriving so now I am left with nothing at all .I would have given 0 stars but was unable to post review 28 March 2016
Rated 5 out of 5 by What's not to like? I am delighted with this purchase. I have had Panasonic models since my first microwave bought nearly 30 years ago. I have found this product to be excellent value for money and the specifications fit my needs perfectly. 10 March 2016
Rated 1 out of 5 by Door Did Not Fit Correctly The product was returned due to the door not fitting the housing correctly. The door was so badly aligned, that this potential safety issue SHOULD have been detected and corrected my the manufacturer - BUT was not 09 March 2016
Rated 1 out of 5 by Worked once. This replaced an old Panasonic which we'd had for years. This one just heated one cup of milk. Next time we used it, it showed an error message. Returned for refund. Draw your own conclusions. 09 February 2016
Rated 1 out of 5 by Didn't last very long We bought the same microwave in silver just before Christmas 2013. Unfortunately, it broke down 3 weeks out of its 2-year warranty. Disappointing - I would have expected a bit more of a Panasonic.... 13 January 2016
