Maytag oven, CRG9700, not heat to correct temperature
« on: October 30, 2009, 10:27:28 AM »
Have a MAYTAG CRG9700AAL gas oven that is not heating to the correct temperature.  It takes twice as long to cook.  The ignitor appears to come on, not sure if it is bad or possibly the thermostat. Swapped the oven ignitor with the broiler ignitor and it appeared to make no difference. Have not tried to check the temperature with just the broiler.

Not sure how to easily diagnose the problem. Found the service manual for Maytag 1997 and newer.  This unit is around 1992, not sure if I need an older manual or where to find one.
Any help is appreciated.

This little movie kinda explains how those ignitors work:

Likely as not, the clock control that times the oven preheat cycle is cycling on 50hz instead of 60 hz, causing the reheat to be about 100 degrees cooloer than programmed.  You'll need a new clock ...this is an EEPROM failure on the clock chip.

If the ignitor is opening the gas valve within 60 seconds after you program a Bake cycle, it is not the ignitor that you need.

He might have to, as I looked the part number 7601P222-60 up on RepairClinic and they are B/O. Bruce lists the clock just below this one (white, for electric ranges) but not this specific one. Perhaps the clock chips are identical.
