RF725GL2 Hotpoint Range - Instructions

This repair is EASY if you know how to use an ohm meter. If not, seek help for this step.

SYMPTOM:
The oven (JKP27WOP3WG or JKP27WP3WG and many ovens like it ) was not getting hot enough. Verifying the cooking temperature with an typical oven thermometer, I was able to determine that the oven was cooking temperature was about 150 degrees to low.

FAILURE POINTS:
There are two logical failure points (1) The oven sensor ( WB21X5301 about $75), or the (2) the controller board (PS238233 about $252). In my case it was the controller board. When replaced the oven worked beautifully.

REPAIR:
As with any repair, you MUST DISCONNECT POWER TO THE UNIT BEFORE SERVICING!!!

Pull oven from the wall:
- Disconnect power by flipping the circuit breaker to the OFF position.
- Remove the top flange / cowling from the top of the oven (it just pulls off)
- Remove two screws under the top flange / cowling
- The whole unit easily slides out, but it is highly recommended that you use two people to place the oven on the floor.

As a diagnostic between these two parts, if the oven sensors measure approximately 1.1K ohms of resistance at room temperature, then it is probably not the sensor. The oven sensor wires are connected to two white wires that run up to the controller board. You need to disconnect the oven sensor to make the measurement. You may either completely remove the oven sensor by cutting the wire (be sure to allow yourself enough slack so that they may be safely reconnected) where it connects to the white wires, OR, (preferred method) if leaving the oven sensor partially installed,
- Remove the top sheet metal cover (10 screws)
- Remove the service connect cover (2 screws - this is where the main Power cord comes into the unit)
- Disconnect the white wires from the controller board (this connector which also includes other circuits is on the left side when looking at the controller board).
- Remove two screws from oven sensor but just let in dangle down so that you can put the sensor in the ice water / boiling water.

Measure the resistance under the following conditions. Your ohm meter should read APPROXIMATELY...
- 1.02K ohms in ice water
- 1.09K ohms at room temperature
- 1.36K ohms in boiling water.
If you get approximately these readings, then it is NOT the oven sensor. If that checks out then re-install the sensor AND the connector.

If it is NOT the sensor, replace the controller board.
- Take a moment to write down the color of the wire to the LETTERING (N, L, G, C / COM,,,) on the controller board. The connectors are in different locations on the new controller board so the wire color to the letter designation is significant.
- Carefully remove the wires one at a time
- VERY carefully remove the keypad ribbon cable from the right side of the controller board.
-- The ribbon cable will disconnect by releasing some little pressure clips on the side of the connector.
- Remove the controller board (4 screws)
- Install new controller board (4 screws)
- VERY carefully connect the keypad ribbon cable on the right side.
-- Make sure that the connector is in the OPEN position first, then,
-- Slide in the cable ensuring that all parts of the ribbon made it into the connector, then
-- Press down on the connector locking tabs.
- Reconnect each wire to the correctly lettering on the board.
-- Again, the connectors MAY BE in a different order on the replacement controller board. Match color to letter.
- Reconnect the (5 wire?) connector that includes the white oven sensor wires.
- Make sure everything looks normal, (i.e. no wires are pinched, remove tools from top of oven area, etc.)
- Re-install top cover.
- Re-install service connect cover.

You can test the unit while it is out of the cabinet,
- Make SURE that all sheet metal covers are in place.
- Flip power breaker to "On".
- Test that oven gets to the desired temp.

I opened the lid, and found that the terminal blocks were burnt, the wires were melted. I ordered one set of terminal block to replace the burnt one, and it worked. Before I started, I shut off the electricity in the whole house to be safe.

First I removed the two screws that hold the element in place. I then pulled the element out about 3 inches and disconnected the two wires

After unscrewing the old heat sensor from inside the oven, I pulled the range away from the wall, got behind it and removed the small panel over the heat sensor. Naturally, the plastic clips connecting the heat sensor to the range wiring wouldn't come apart, so I eventually had to simply pry them apart with two pliers. Then, naturally, the new plastic connector clip on the replacement part didn't match the clip from the range, so I had to cut off both receptacles and strip the wires, then used the provided wire nuts to make the connections. After that, it was easy, just secured the heat sensor inside the oven and replaced the panel. I didn't push the range back against the wall until I tested the repair. It worked fine!

TURN OFF ALL POWER TO KITCHEN. Took off all burner coils and plates below them. Lift hood. Locate part. Remove old part and replace with new part in same way as was previously installed. The wire that comes with the kit is actually too much wire, but just arrange it the best you can and leave it....no big deal. I didn't have a magnet, but needed one. The wire from burner coil to switch runs through a harness which is screwed on to the body of the oven (below the range). Be careful NOT to drop it behind oven when taking it out. I dropped it and took forever to get it. That turned a 20 minuate job into an hour and a half. Otherwise this is an easy job that anyone can do. Refrigerator compressor is next. Have fun.

1. Removed the back panel.
2. Disconnected the wires from the old switch while connecting wires to the new switch one at a time.
3. Installed the new switch and broke off the excess metal on the post which fits into the burner knob on front of the range.
4. Replaced the burner knob and replaced the back panel.

I removed the unit from the wall,removed the back panel to access the wires to the sensor,cut the plug off of the new sensor and strip the wires back,used the wire nuts to attach the new sensor,put all back together and slid back into the wall and works excellent.

As has been said shut down unit,Breaker fuse.If you do not have install info.Get a copy on line. If you have another set of hands it would not hurt.! this has been stated before. Remove door, Remove 4 screws , to slide unit out,I used a saw horse with some cribing secured to the horse to get height, Pull the oven out so that the two front supports are on the saw horse,and the back two are up to the edge runner.I used about a 1 ft stool for working height. Remove the top elec. cover sheet metal 2 screws. You will see were the wireing runs down the back. Get a small mirror,and flash light. Look down the wire opening in the back, you see the sensor connection ,I made a hook out of a coat hanger to grab it with. Pull it up before you disconnect it ,tie a piece of string to the sensor side of the connector , use 2 Ft. then disconnect remove two screws from inside the oven. And remove,sensor tie string on to new sensor connector pull through and connect.on top.Then replace everything cck every thing Twice!Doing this i didn"t have to pull the unit all the way out! LATER GOOD LUCK!

It was very easy I removed two screws unpluged the sensor and wire spliced it together and also replaced the modual on the top of the stove and it was that easy.

After months of buying the wrong parts & cost I discovered this site So easy to order & quick delivery, plus very easy installation. Thank you. I also wanted to add that the reps (Tanisha & Matthew) were extremely helpful & informative. I can only hope all the reps equal their performance. I will definitely be using this site, before any other source. Knowledge & cost is also important to me & that need was met. Good job!

tries brazing ends back onto posts...it did work but still not as good as I wanted. Bit the bullet for 100.00 and bought 2 new burners and drip pans. Only regret was not buying the two smaller burners with pans. Smaller ones still work but the new ones work like brand new and an added benefit is they make the stove look brand new!! Very pleased with decision to buy!

No problem installing oven sensor, but I diagnose the problem wrong, I need to change(ERC-11)control p/n wb27k5140

Disconnect power. . . Remove control panel, pull wire connectors,[note location] remove old switch, install new, install wires, snip stem to length, set knob . . . Turn on power - works. [Note this is a live part even when not connected]

Ever the optimist, I'd replaced the burner on this relic of another time to no effect. That left the switch. You guys should know that when a burner element goes bad it can take out the switch. I should have put a meter on it. Wehn I looked for a replacement a few months ago there were still factory parts available, but they were $80 or so and I wasn't inclined to risk that on a 40 year old range. I offered to replace the raange for my daughter as a Christmas present but she like this old thing. It was an unusual size with a pan storage compartment on the left. I went on line and found this universal replacement for about $25 delivered. What the heck. I ordered it and it arrived within a week. I pulled the stove out, killed the breaker, pulled the knob off, used a nut driver to take ther rear panel off, two phillips screws under the knob hold the switch in. The terminals on the old switch are in a slightly different order but are clearly marked L1, L2, H1, H2 and P. The P is the power and has a smaller terminal so you can't put it on the wrong one. Just examine the old switch ( it was marked the same way) take off the L1 and put in on the L1 of the new switch and so on, make sure you use the correct knob adapter to fit your old knob and break the switch stem to the correct length. It will break easilly if you hold it with one pliers and break it with another. Screw the new switch in place with he old screws. At this point, I closed the breakers and tested it. It worked fine. I turned the breakers off again. Buttoned it up and slid the stove back into place. 20 minutes tops. Great product. Good for another forty years.

Replaced the clock control lens with buttons. Saved us from purchasing a new oven. A Sears repair man told us to get model number and look online for the part we needed, and we found PartsSelect. Great! Very happy.
