We have had our Dacor double oven CPS230S for 15 years and just stsrted to get error code F1. We played around with the control panel buttons to turn it off and finally succeded. I began reading the treads and am not very impressed with what lies ahead. Sounds like a cable upgrade may have fixed the problem, has the cable feeding the control panel been improved?

I read through these posts and ones on Appliance Junk as well. I removed the faceplate on the inside of the oven where the door closes and I looked carefully at the microswitches for the oven clean lock and noticed they were fine.I did clean them anyway but this did not correct the F1 error However, just to the right of these are the two oven temperature sensors, and they were covered with dirt and grease and it appeared as if two of the terminals could possibly be shorting together. These are black rounded caps with a small red reset button in the middle and each one has two wires with blade connectors attached to them. I cleaned them with a toothbrush to remove the dust and grease and the F1 error code did not reappear. I hope this will help some of you out there as well.

I too have been having a problem with my Dacor and the F1 error. I haven't looked into the door switch, but plan to. I too have had to resort to turning off the breaker when the range is not in use. I have noticed a clicking sound from the front panel. Once the clicking starts, the error and beeping isn't far behind. If I need to use the cook top, I can cheat the system by setting the oven to Bake at 135 degrees. The element is barely on, but as long as the oven is on, the error is cleared. More to come.

The F1 error is due to a faulty keypad. Unfortunately, you can not buy just the keypad which can be removed from the whole plastic bezel assembly. Instead, it is sold as one unit which runs around $300.

If you don'thave $300 to throw around, the best and cheapest solution is remove the speaker (the black round thing in the back) from the circuit board. This wil take away the annoying beeping sound but the F1 error occur. That is okay because the oven still work with the F1 error.

Good luck.

"-F1- Alarm “System Watchdog Circuit”
ERC Self-Diagnostic circuitry has detected a failure in the bake/broil system. Any portion of the ERC, relay board, touch pad, heating elements and related wiring may be at fault.
How to diagnose/repair potential cause:
Step 1: Disconnect membrane from ERC. If an F-1 alarm is not activated within 30 seconds, check membrane function test points with an OHM meter. (refer to page 20 of the Diagnostic Test Manual) If the membrane test switch fails, replace membrane. If membrane test is good, continue to step 2.

Step 2: At ERC check for 24 VDC between J2 pins 1 and 3 for upper/single ovens or J5 pins 7 and 10 for lower ovens (when lower oven is not in a cooking/clean mode) **Note: F-1 must be showing in the ERC/Clock Display. I you read 24 VDC at those test points, replace ERC"

My issue seems to be resolved at Step 1, which means that only the keyboard pad is shorted somewhere.

There are two alternative ways to fix this:
a) Check the front bezel. If it's NOT broken, cracked, etc.chances you can get away with just a new keypad. Order and replace just the keypad, which for RSD30S (black) is part number 86063B.
OR
b) If the front bezel is chipped, broken, cracked, I'd recommend replacing the front bezel, which also comes bundled with a keypad built into it. The part number for the bezel for an RDS30S (black) is 76480B.

I'd also recommend checking this web url as well:

(Someone somewhere said that humid weather makes intermittent F1 problems appear more, this is perfectly logical with a shorted keyboard membrane.)

IMPORTANT: An appliance technician also told me that you should never use the self cleaning feature on this oven as the 800F+ temperature that self cleaning function heats the oven to almost guarantees that the keyboard membrane or control circuit/clock will be fried and you will see the F1 appear.
