Troubleshooting an E-92 Error Code

Overview

There are two possible reasons for an E-92 error code:

• There is a shorted component leading to the 24 VAC fuse on the I/O board to be open.

• The solenoid valve is stuck, causing it to draw too much current.

Procedure

Shorted Component

SHOCK HAZARD To avoid electrical shock, perform relay checks or transformer checks as described as instructions.

The following checks are performed with the wall circuit breaker closed and the main power switch in the ON position. Extreme caution should be taken. Make connections before applying power, take reading, and remove power before removing meter leads, or electrical shock could result.

1. Check the voltage from the transformer to the board. It should be 24VAC, otherwise, replace the transformer.

2. Check voltage on 24 VAC safety components (high limit, drain switch) connected to the board. Disconnect other 24v components (contactors) then reconnect one at a time to determine which component causes the E-92 error code.

3. Replace component that does not read 24VAC.

4. If the E-92 continues, replace I/O board.

Solenoid Valve is Stuck

Is the fryer getting an E-92 error during the first cook cycle of the day, and not occurring for the rest of the day?

During the first cook cycle the solenoid is turned on, but when the core cannot move this draws high current and a few minutes later the fuse opens up. The steam going through the pressure solenoid eventually warms it up and the core is able to move. Overnight the fryer cools down, the particles in the solenoid solidify, and the situation repeats the next morning.

Check and clean the solenoid valve before the solenoid is turned on. Refer to Replacing the Solenoid Valve for information on taking apart the solenoid for cleaning.
