Comfortmaker RPJ2 igniter and transformer output


I have a Comfortmaker RPJ2 that went out today. The blower will start up but the igniter (Q3400A 1040) would not heat up. I replaced the igniter/sensor and it ignited once then would not work again. I checked the voltage of the leads of the igniter from the gas valve and there is power during the cycle but the voltage is at 30v not at 24v. I also checked the transformer (HQ1008782PU) and the output voltage is also at 24v. Is the transformer bad or is it normal to output 6v higher? Also will the higher voltage blow the igniter?
Any suggestions are welcome.
Thanks,
Keith
