Pat for Model Number MGR5870adw To try an improve our gas oven heating I bought your part #AP4012072 (12400035) , a flat style oven igniter kit for $30.97 on 2/24(order #3181830), and installed tonight 2/26. Unfortunately oven still seems to pre-heat slowly sometimes, sometimes with a gas smell. The old igniter had an ohm reading of 147 vs. new's 257 but it wasn't an open loop/broken. The oven sensor had an omh reading of 1079 or 1.079 so it wasn't open either. How long should it take to pre-heat to 350 - ours can take 20 mins? Is there another issue? Oven valve? Seems to be only 1 valve breaking gas line IN to top burners and oven - burners work fine. Pilot? Like before new igniter, oven sometimes heats up quick and other times not. Previously too it sometimes took forever to cool down - even clicking (on?) after we shut it off. Control panel - how can I take a reading on control panel? Thx
Answer Pat, To take a reading on the control board you would be looking for voltage. The proper voltage is getting to the control board if the power is working and the oven is coming on and cycling. There should be 120 vac to the board. You could also check your oven sensor which should have an ohm reading of 1090 ohms at room temp. If it is outside the range of 10 percent then it is faulty. The clock would be the most likely cause with it being as erratic of sometimes quick and sometimes slow along with gas firing when the oven is off. Read More...
