HelloooOOO- Samarailand......

Well, Im back with new adventures!!! Today I ran across an Old school Frigidaire Double wall oven, Model # RGCF97ew. The top oven wasnt heating in bake or broil. The light comes on and off like its supposed to and the fan blower fan comes on when You turn the selector knob. It appears everything is working but the heat. So... WHERES THE HEAT??????


Both bake and broil elements look to be in good condition (as is the rest of the oven), but when I opened up the face to get to the switches and tstats... WHAT A MESS!!!!!! Wires were Everywhere. And the parts I saw... Well lets just say- Im just not THAT old!!! Anyhue... I need some help with understanding this one and finding out if theres a reset on it or not. FRIGIDAIRE Couldnt help. They have no info on this one. (yes Im authorized). ITs a pretty cool oven. The owner would like to keep it and I would LUVVVV to fix this one if possible. ANY OLD SCHOOL TECHS OUT THERE WANNA SHARE THEIR WISDOM?????? This 'Young(er) skewl' Tech wants to learn......

Parts are coming up NLA - does the lower oven work? Did you verify 240v supply ?

Looks like capillary thermostats - might have a diagram pasted on it (on back or inner panel etc)

p.s.- the oven is younger than I am

Does this have a mechanical clock? If so is there a manual setting. Do you have a wiring diagram?

So kdog you remember frigidaire "flair" models?

Not in particular, but I remember many ovens with mechanical t'stats, T.R.O's,T.R.C's etc. Also remember wasting time to inspect them only to find a bad fuse/breaker/wire connection etc

Flairs had two side by side ovens that had clear glass doors that pulled forward and hinged up. The monotube surface elements slid out on a drawer.

Some of these old units also had hot wire relays.

Yes Kdog, the lower oven works fine. The owner would like to keep the oven and is willing to lose his lower oven if it is the Tstats. Im just kinda stumped over how to go about this one. The wiring behind the controls are a full fledge mess and as much as I would like to assist in geting his top oven working again... well... Im a bit intimidated. Scared I mite mess sumpin up!!! But I like the challanges and would like to get sum old school wisdom. Plus, Its a cool lookn oven. and should b KEPT workn.

NCARepair... the clock is digital. behind it looks like 3 relays. wish i woulda took pix. mayb ill go back and do that. But RegUS's diagram (at Sears) shows it. (Sort of)... and NO KDog - didnt verify 240v. said I would do that when I came back. But wouldnt that affect BOTH ovens if there was a problem, or does the voltage split? If not,Besides at the plug and terminal strip on oven, where else would I b looking for 240V? WHUT WOULD YOU GUYS (or Ladies) DO??? Question.... whats a" hot wire relay"??? what was/is it used for??? And is THAT what is behind the clock????

A hot wire relay is used to cycle the high amperage circuits, (heating elements), using a low/110 volt signal from the t-stat. When the 110 volts is supplied to the hot wire relay a bi-metal will heat up causing the contacts for the element/s that it controls to close, energizing the elements. Keeps the high amperage load off the t-stat cycling contacts.

Here's what a "Hot Wire Relay" is and looks like:

They were used mostly in the old GE's and Frigidaires. This one that I found to show you what they are is a Bosch part - I've never worked on a Bosch range/oven so don't if it is something that is commonly found on Bosch ranges/ovens or not.

An older Whirlpool built-in oven that I worked on recently had what looks exactly like a RobertShaw infinite switch but without any shaft - basicly the same function of this hot wire relay that you are asking about, the RobertShaw infinite switch style hot wire relay is also used in Thermador ovens.

Well, as we always say..."if ya want some old school knowledge, yea gotta go to Willie!"

Er...maybe we don't say this...but its true.

Yeppers, I have revived many a Thermador pro range with a hot wire relay, but it usually looks like the one in the photo.
easy to diagnose, though. If you are getting yer coil voltage from the Tstat, but she wont close...slam dunk.
not sure if this dinosaur has one,

My gmaws old house has one of those "lift up-pullout" friggys...beautiful machine. Still works except the clock...
