Product review (5 stars): Repair help for a Frigidaire dual fuel range model GLCS389EQB that was not heating properly
This review will hopefully help somebody not have to wade through the internet for a long time and thus shorten the repair process. We have a Frigidaire dual fuel  range GLCS389EQB that suddenly stopped heating. We initially thought it could be the bottom element which brought us to this page since the other sources online appeared to be cheaper but when one factored in shipping, Amazon was almost the same price thus it was easier to order since all the info is already in Amazon for shipping and payments.

We received the element and replaced the old element only to find that the oven still did not work. We could have returned this element but felt that a range that is almost 10 years old could use a new element so we kept it. Since the element was new, the next logical source of the problem was the control unit. Although I could not find a source out there that indicated this, I found that the control unit is not cheap. In fact, it is $243.32 with shipping direct from Electrolux (Frigidaire's parent company). Ordering was easily done via the telephone and the cost was almost identical to many of the part places online.

The control unit came but had no instructions. Using the online manuals that are available, it was relatively easy to see how this needed to replaced. I have included some pictures for the DIYers out there to help save you the cost of a repair service call. The most difficult part was the removal of the wiring harness on the control board. A small screwdriver was needed to slightly pry the plastic back to remove the harness. The other curious part was the ribbon wiring which had a locking system that needed to be lifted up to release the ribbon and pushed down to lock the ribbon back in place.

The entire job took less than 15 minutes. Be sure to unplug the stove. Also, it made sense to snap a picture before you remove the wires to be sure you put them back in the same place. While we were at it, we were able to clean the almost 10 years of cooking crap that collected. Fortunately, it was not too bad. Good design by Frigidaire IMHO. We love this range and felt that a simple $325 investment was cheaper than buying a new range. Not paying for a service call made this a no brainer.

Hopefully those who have problems with their Frigidaire dual fuel range model GLCS389EQB will find this page. Good luck!

BTW- the part number for the control panel is 316418731 CLOCK/TIMER, ELECTRONIC, ES510 and the phone number for Eletrolux is 800-599-7569. It is best to give them the model number of your range and they will tell you the part. The customer service rep stated that the likely cause of the lack of heat is first the element and then the control panel in that order.

Also, this element fit perfectly and arrived very quickly.
