GE Cooktop Error Code 173

Error code 173 on a GE cooktop indicates a CPU failure on the display board. The display board's microprocessor controls user inputs, cooking zones, and power management, and this code means that processor has encountered a fault it cannot recover from on its own. The first step is to recycle power to the unit. If the code returns, the display board needs to be replaced.

Start by cutting power to the cooktop at the circuit breaker for 60 seconds to perform a hard reset. If the fault clears and does not return, no further action is needed. If error 173 comes back after power is restored, the display board has failed and must be replaced as a complete unit, since the CPU is not serviceable at the component level in the field.

If the error clears with a power reset, there is no parts cost involved. If the display board needs to be replaced, parts alone typically range from $80 to $250 depending on the specific cooktop model. Adding professional labor for diagnosis and installation, the total repair cost generally falls in the range of $150 to $400.

A power reset can clear error code 173 if the CPU experienced a temporary soft fault. Turn off the cooktop at the circuit breaker and leave it off for at least 60 seconds before restoring power. If the error code returns after the reset, the fault is persistent and the display board will need to be replaced.

A display board CPU failure means the control system is not functioning normally, which makes it unsafe to continue operating the cooktop. Cooking zones may not respond correctly to commands or may not shut off as expected. Do not use the cooktop until the error has been resolved, either by a successful power reset or by replacing the display board.
